I've been using Win7 since it came out (thank you amazon 'free' release day shipping). I like it for the little things. Mostly love the enhancements to Media Center since my laptop is my mini-htpc (along with the external drive that holds them all). Got Win7 back when they had the pre-sale for $50 so I couldn't refuse that.
I also somehow got Win7 to give me a BSOD already

. NO CLUE how I did it because it was sitting idle at the time.
