Windows 7 is already better than Vista and it's only in beta. It uses significantly less resources and runs much faster on less "beefy" systems. They basically stripped out most of the crap that hindered Vista machines' performance, like prefetch (evil). Who cares how fast they boot up? That's so superficial in the grand scheme of things. So far, the only problem I've had with the 64-bit beta was installing the drivers for my HD4870, which is to be expected. Yes, instead of fixing Vista they made a new OS, not a huge deal if you like Vista and want to keep it.
