So yeah, I had an action-packed Saturday night installing W7 on my desktop

So far I'm noticing it is way faster to boot and wildly more responsive than Vista. I did a clean install, so I'm still filling in the blanks w/ software, but it's been really painless so far. The only driver I had to chase down was my nigh-vintage sound card, but it's out there and Creative's proprietary (actually semi-useful) software looks more developed on W7 than Vista. I ran Windows Easy Transfer beforehand, so most of my old preferences and file structure were back in place in ten minutes, despite the clean install.

All the aesthetics are much improved over Vista, and the new taskbar feels positively OSX, without the limitations. Overall, where Vista was a dubious improvement over XP, this is an undeniable upgrade. Even the artwork with the included themes is about ten times better.
