One non-impressive bit of Apple new is that the Virginia Tech supercomputer built of G5 towers is now offline waiting to be replaced by G5 Xserve rackmount computers.

That's horrible press, and I'm impressed that Apple's been able to bury that fairly well. What good's making a supercomputer if you have to turn it off to upgrade? Couldn't they've done it piecemeal? Make another in another room? At any rate, that's hardly a very smooth transition, and not very Mac like at all in that sense.
