    With all these performance-improving things, shouldn't performance actually, you know, be improved?

    Many have fallen into the trap of building "intelligent" cache systems that perform worse than the "dumb" cache systems. Remember, every MB of RAM caching an app that you might use is not caching part of the photo that you are editing; caching is subtle work.

    So, as I have not used Vista and have no plans to (I'm with Linux), a question: Can anybody tell me that they put Vista on their computer and things are now noticably faster? I've heard from people with the opposite experience, now I'm soliciting evidence that all these Ready* things actually help people.

    No seek time. That's the main benefit over a hard drive. If you need lots of data, it's not that great. But if you just need a few bytes, it'll be faster than asking the hard drive. Ask the USB stick for the first few bits of a page, and the hard drive for the rest, and you get the best of both worlds.

    At least, that's how I'd design it if I were much of an engineer ;)
