    Absolutely. That's why I felt it was so important to comment. The Apple hardware has been standstill. I don't like this anymore than the other guy, but unfortunately it's an inescapable fact. A select few of the people here have become complacent over status-quo, old technology and don't even realize it. These people are doing both themselves and Apple a disservice.


    I also think it's very important in this day in age to keep an open mind. If we look back at history, the m68k machines lagged behind x86. Then along came the 601/604, that turned the tables. Today Mac users are once again behind the times in hardware. Don�t worry though, it won�t always be like this. By the time you are ready to buy a new desktop I�m optimistic that Apple will have a solution to the G4 problem. Also keep in mind that within that 1 year Mac OS X will continue to evolve, it�s only going to get better.

    But also keep in mind, (and I don�t think this will be the case) but if that does not happen, and in a year from now you see the Mac platform stuck in the same boat as it is today, it would be incredibly foolish to invest thousands of your hard earned dollars on one.

    Good luck!

    I wouldn't be so smug if I was you. Looks like Austria uses over 60% imported oil and gas for electricity manufacture (http://ec.europa.eu/energy/energy_policy/doc/factsheets/mix/mix_at_en.pdf)... that Persian Gulf political turmoil must be pretty exciting for you guys, yes? Probably costly too.

    You're also reliant on those nice people in Russia to keep their natural gas pipelines open (http://en.wikipedia.org/wiki/Russia–Ukraine_gas_disputes), aren't you... being land-locked and all.

    you know what actually is costly ? the US policies in regard to Iran: it actually prevented developing the south iranian gas fields for use for european earth gas users since the US embargoes any company doing business with iran in excess of 10 million dollar ... and because of the US preventing alternative sources we are depending on Russia which had been a consistent supplier for more than half a century

    nice distraction from your own argument ... where is the terror and war in which austria is involved because of the lack of nuclear energy ?
    i would rather claim that nuclear power plants, construction of such powerplants, nuclear fuel production etc. bring forward a lot more international conflict

    Therein lay the problem. Most people are using the music illegally.
    The record industry is right.
    In your own analogy of Joe Public burning a track on his wedding video.
    Guess what? when he distributes those copies to wedding guests he breaks the law.
    It's illegal for him to do that. It is stealing. He pirated it.
    The problem is we have become so used to stealing that we don't recognize it as such anymore. We justify it away.
    Almost no one would even consider it to be wrong if they bought a cd copied it and gave it to their friends. It is wrong. It's stealing/pirating.

    It is wrong? How so? If I burn a track for my wedding video, yes, I'm technically breakeing the law, but there is nothing immoral about doing that. No one is losing out on any money. No one is being hurt. He isn't stealing anything. He's breaking a copyright law that makes no sense in that case.

    But it can be fixed by possibly: Encrypting (or Changing the way it is encrypted) the AAC file on the transfer from itms to the player.
    or force the player to send the authorize code to apple to wrap on <i> their</i> servers before send it back to the player.

    If they do the server fix it'll take more than a day.

    And it will take Jon a day to figure out how the iTunes client generates that key and spoof it. Again by definition DRM has to be insecure, because the client must have all the information necessary to break it.

    In interviews Steve Jobs has gone on record saying that unbreakable DRM is impossible. What you're seeing from Apple is a "good enough" strategy. After all, they don't really care, it's only there to appease the RIAA.

    Does anybody have more of an idea on how the DRM wrapping is done and how the undrmed file is transfered?

    There's a good overview of what's happening at Ars.

    Basically the issue (and I hadn't thought about this) is that the song has to be individually encrypted for each client; that's how its made playable on your system not other people's. Because they're using Akamai to cache and distribute the files they can't distribute pre-encrypted ones! (The analogy is it would be like libraries carrying a copy of the book for everyone who might borrow it). Apple can't link everything back to their servers as you'd bottleneck it.

    Instead its your copy of iTunes that's actually adding the DRM (and that's probably why the new Motorola phone won't let you buy directly from the store, it can't add the DRM).

    It's an interesting problem. I would bet you will find this hole in WMA stores for the same reason. Of course Jon prefers to target the source that will get him headlines.

    Apple will make another "good enough" fix to block it for another 6 months. But they really don't care. Although externally they "care", I bet internally it doesn't particularly bother them because ITMS is so big that the record companies can't afford to pull out of it.

    seccondly, it makes no business sense. Apple knows people are holding out for merom.

    not really. People are buying macbooks in droves. Only a very few people (the numbers seem inflated on a board like this) are holding out.

    I can build my own PC for way less than the cost of a mac so I'm switching to XP, blah blah blah

    really?? You don't say! Well stop the presses; apparently it costs less to custom build a PC than to buy a premade computer! My goodness, this is news. I think Apple, Dell, HP, Sony, and all the rest should shut down their factories now because it's clear that they can no longer do business in light of this development.

    But you know, now I'm thinking that maybe some people don't have the time, know-how, or patience to build their own PCs. And I'm thinking that they like having warranties for when something goes wrong and they don't know how to fix it. And I'm thinking that for the majority of users the friendliness of the OS is going to be about 1000x more significant than having the latest omg-wtf-bbq-roxxor!!11!1! graphics card. So good for you that you're happy with a high-end home-built XP box, but please don't act like people are stupid for going with a professionally built and supported machine that does everything they need and runs a better OS.
    -------
    Moving on... the issue of a headless-upgradable-imac (which really isn't an imac at all because imacs are pretty much defined as being all-in-ones and non-upgradable, so I'll call it a low-end tower) has come up a lot recently. Everyone in this thread seems very sure that apple will release such a product, but I'm quite skeptical. I don't see who it appeals to. Demanding gamers, as macenforcer points out, are much better off building their own machine. Pros will want a true pro tower, not a stripped down version. Students would do better with a space saving, all-in-one design like an imac. "Average home users" like my mom will never upgrade anything (except *maybe* the RAM) so should get imacs or mac minis. The target market for this low-end tower seems to be knowledgable consumers who like upgrading. There are many such people on this board, but they're a comparatively rare breed in the real world.

    Also, apple is not going to have very high margins on such a machine, I'd wager. After all, it's a budget tower, right? But the people who buy them are going to keep them and upgrade them (with 3rd party hardware) for a very long time. So apple has one initial sale at low margins and then doesn't see that consumer again for years. If I were apple I'd either want to make a really big sale up front (like with a mac pro), or sell a not-very upgradable machine that will have you coming back in 2 or 3 years rather than 5 or 6.

    So IMO, while this low-end tower would fill a gap in apple's line up and be ideal for many on this board, I'm not sure it's a gap that many consumers fit in to, or that apple particularly cares about filling.

    A lot of these questions come down to whether Apple is going to market iTV as a satellite/cable killer.

    Scenario A: iTV is a way to watch movies and shows in your iTunes library and (for $1.99) watch an episode of a show you forgot to DVR or that you just really like and want to own.

    Scenario B: Apple morphs its season pass feature for TV shows into a subscription service that is priced competitive to cable. Movies are available in HD for $3.99 for 24 hours.

    Scenario A doesn't really give me anything I don't already have, and I'm not going to pay $299 for the privilege of buying movies for $10 that I can PPV for $4. But Scenario B gives me a way to drop my cable package altogether; it's similar to the way mobile phones allowed people to drop local phone service.

    because everything on cable is available at itunes. your analogy is wrong.

    but what I really wish is for people would stop demanding what they want it to do so they'll buy it and focus on what it will do and how it will do that. I guess that's too much to ask.

    on another note, I don't understand what the big fuss. when do most users stop gaming long enough to watch a movie.

    I like computers just as much as the next geek but when you break it all down what can't you do with computers and OS's from even 5 years ago that you can today? In truth the only real benefits are that Windows and Mac systems are faster and more stable than they used to be. For Macs to make any inroads more innovation is the key. They cannot compete on price/performance and never will. Moving to x86 could help of course. Note that most people don't buy Macs because of price and not because of performance issues.

    So with this in mind if you set aside the small contingent that truly needs faster Macs for their jobs in professional settings, the Mac really needs lower prices and more innovation. Do that and Apple will have a winner that they would need to open up the clone market again just to be able to make enough of them.

    Frankly this whole benchmark argument is stupid for most of the people here. Benchmarks should be used as nothing more than a guide and you should have multiple sources if you want to base a purchasing decision from them alone. Too many people treat them as the end all be all.

    One point you are missing is that I can upgrade my PC 5 times over and still have the cost be lower than buying a new Mac. So a mac can run modern apps 5 years later. For the same price, I can get a PC, drop a new HD, video card, and CPU in a few years later and then end up with a leading edge PC, and not a bleading edge mac. My B&W G3 isn't even upgradable to the speeds of the current iMacs. With a PC a new mobo and CPU will get me into whatever is the current CPU class....

I still have faith that the G5 will make up for this gap.

    As for OS X vs Windows 2000, I am not as technically aware as the above poster, however my own experience in a large office environment with heavy networking is that Windows 2000 has failed us. We are switching to Unix and Sun, because we can't afford the down time that windows 2000 is giving us, the cost advantage of windows not withstanding.

    I have not come accross many large computer operations people that will tell me that Windows is a replacement for Unix. Not unless dealing with small size and limited budget.

    To clarify, I was referring to Windows XP and Mac OS X on the desktop, not server. I have had excellent experiences with both in terms of stability. As far as the Windows platform on the server side, again, the magic is in the software. I work for a modest sized isp, and we recently transitioned all of our production servers to bsd and linux blades. All of our web/dns/mx/mail/mrtg/etc machines are Unix. The result has been they are more reliable, and easier to maintain, not to mention the substantial less total cost of ownership.

    Pretty much like a weather vein or TV aerial. Provides a couple of hundred watts at 24V or 12V. I was thinking about one for if there is ever a blackout (ie a drunk hitting a power pole, it's happened) instead of needing a petrol generator.

    Every home generating 500W of their own wind power with one of these little things on their roof in a city of Los Angeles with a million homes = 500,000,000 watts. As well as a solar panel at 500W too is up to a billion watts not required from any central power source.

    California is making great strides in this area. Through creative financing, tax breaks, and fairly high electric rates, quite a few people have solar. It's especially important here in the summer when electricity use is at its greatest.


    However, the one thing that nobody has brought up is that evil word..... CONSERVATION

    Not using electricity is a lot cheaper all around than building a new power plant, no matter the fuel source.

    I find this whole discussion slightly amusing, mostly because of the apparent need to draw a distinction between "professional" and "consumer" based on slight clock frequency differences. To me, a professional platform is defined by its configurability and flexibility. A professional platform is simply one that can be configured to fit the customers every need. Although CPU performance is important, it's hardly what I'd call the defining factor of wether a system is to be regarded as "pro" or not.

    I don't see any reason why a cheaper Mac Pro with a single 2.4GHz Conroe couldn't remain a machine aimed at professionals. Or does it have to have an outrageous price tag to qualify?

    The whole concept of drawing a line between pro machines and machines for mere mortals seems a little "old". There's nothing really special about a PowerMac or Mac Pro anyway. Put a mid range CPU in the machine and it fits the regular consumer just as well as a professional not demanding the absolute top end CPU performance.

    Maybe I've been damaged by the PC worlds lack of "pro-obsession", but I think it's a healthier approach.

    Merom will underperform a Conroe under equal high loads because of thermal constraints (in unmodified systems).
    It will? Do you have any source for this info? An Intel rep has said that Merom and Conroe are identical, except for a few differences having to do with p-states. This is unlikely to hinder performance at full load, so where did you get this contradicting info?

    Also, the largest part of the power savings between Merom and Conroe are likely to come from reduced core voltage. You will probably be able to come very close to Merom power levels by simply reducing the core voltage of a similarly clocked Conroe.

    Same logic: if I take someone else's car, and drive away with it, I'm stealing it. But if I create an identical copy of the car (using a replicator I got from Star Trek) for myself, have I stolen anything? From whom have I stolen?


    If you go to a concert, theatre play, any kind of performance or into any of fee-charging class or course and smuggle yourself in through some kind of backdoor without paying for the ticket or the course, did you steal anything?

    Not according to your logic.

    They offer an unlimited data plan for one device. There's nothing illegal about it. By sharing that data with other devices you are very clearly and very simply breaking the contract.

    Please point that out in the contract, know it all.

    Guess what, it isn't there.

    Go look up the word Unlimited in the dictionary. Internalize and understand it. Come back here when you're done. Then come into a court room. Id like to sit back watch you (as I will eventually be watching AT&T) dance around the clear and concise definition of the word.

    I've engaged in long, drawn out discussions with my legal pals about this very issue for several years, and they all agree it would completely impossible for AT&T to get out of court unscathed over this word "Unlimited"

    Most of you people don't grasp the significance of the word in this case, which is not at all surprising given the crowd. (young and/or naive).

    Most also think that because AT&T includes fine print in a contract, they can enforce it however they wish...which of course is a laughable fantasy to anyone who has sat through the first day of contract law.

    Nope, it doesn't. Besides, I already told you in another thread that Intel agrees with my intrepetation on this matter. The see dual-dual systems as 2-way systems, whereas according to you, they are 4-way systems. Are you saying that Intel does not know what they are doing?
    Intel and AMD push hard to make sure that a dual-core processor is *licensed* as a single CPU. This is because there are a lot of big software packages that are priced according to the number of processors, often much more expensive for a 4-way than a 2-way.

    The CPU makers wouldn't sell as many multi-core chips if the systems were much more expensive (in TCO) than single-core chips. Therefore they pretend that a "processor" is what can be plugged into a socket. The software sees that there are "physical processors" (a package with pins) and "logical processors" (the CPU that we've been familiar with for decades, which requires SMP hardware capabilities to be useful with 2 or more).

    They say that software licensing should consider the *physical* processor count for licensing terms. (For example, XP Home will run SMP on a dual-core, but not on a dual-socket. XP Pro will run 4-way SMP on a dual-socket quad-core, but not on a quad-socket quad-core. Microsoft licensing looks at the number of physical processors, while of course the software runs according to the number of logical processors.)

    So, Intel/AMD/MS have an agenda that requires them to distort the meaning of the word "processor". They have to warp the word "processor" to justify the licensing stance.

    Nearly forty years ago psychologists declared homosexuality was not a mental illness

    I don't know whether homosexuality is a mental illness. But I do know that doctors and other professionals sometimes make mistakes.

    About 25 years ago, an acquaintance of mine told my mother that for about 15 years, a doctor treated her, my acquaintance, with the wrong medicine because her illness had been misdiagnosed. Unfortunately, after another doctor discovered the misdiagnosis, he also discovered that the medicine was worsening her symptoms.

    When I was about 17, my optometrist realized that, if I kept wearing the glasses an opthamologist prescribed for me, they would blind me. The optometrist prescribed the lenses I needed and corrected the vision problem for which I visited him. Thanks to the optometrist, I can drive.

    It is no longer understood to be the case that homosexuality entails a necessary harm to the participants or anyone else.
    Dr. Joseph Nicolosi disagrees. So does another psychologist who gave a lecture series called "Homosexuality 101." If the lecture series interests anyone here, I'll post links to its Youtube videos, or I'll try to explain the lecturer's theory. But I prefer to let the lecturer speak for herself because I'm not an expert in psychology.

    Quite the contrary, same-sex couples are known to form loving, supportive, monogamous relationships every bit as profound as those enjoyed between men and women.
    Although that's true, it doesn't show that homosexuality is a healthy quality to have.

    However it isn't tyranny because the government isn't actually depriving them of liberty, merely not supporting them.

    You will say anything to rationalize your prejudice, won't you? I have trouble believing anyone is as dense as you pretend here.

    Just in case, though, the government offers legal concessions to men and women who legally (not religiously) commit to a marriage. It refuses to extend those same concessions to same-sex couples, and can demonstrate no legitimate state interest in this discrimination. That is denial of equal treatment under the law, and is unconstitutional.
