...I still don't buy it. The Golden Age of the "chip" as we know it has passed. Dual-core, quad-core... sure, okay. But then the bus is the bottleneck, and the same problems that are cropping up in the cpu are going to crop up (are cropping up) there as well. There are probably numerous alternatives, and there probably have been designs for alternatives for years, but the money is still in making basic chips that kids can plug into their asus mobos and go nutz playing the latest game. We're going to see more parallel(ish) stuff, for sure (dual, quad, etc.), and we're probably going to see more attention put toward writing good code (at last), but I don't think we'll see the sort of speed boosts we saw from aorund '97 to '04. I'm totally willing to be wrong about this, but there is no great indication that things are going to change in a fundamental way any time soon.
And a standalone box doesn't have to be any more or less flexible than a conventional computer. It would probably be based on some brand of linux, with a proprietary GUI, and little or no access to the OS itself. But you've still got software/OS, and firmware/BIOS. That's it. If VSL wanted to update something, it could be as simple as applying a patch -- in fact, it could even be done automatically online for you, without you even thinking about it.
