@AndyC: I'll have to remember that the next time Granny's current PC and future PCs blue screen... "Hey Granny didn't you know it's for the greater good? You should be happy your PC is blue screening."
A lot has been said about what Microsoft would fix or improve before release and I just don't see that happening. They're trying to be a lot of different things to a lot of different people and it's feeling a lot like Vista -- drivers et all. We'll see what happens upon final release.
