Anyway, have been running 7 fulltime on my Thinkpad since the 6594 (or somesuch number) build leaked. Tried to get through the madness yesterday and must say it was amusing hitting F5 on the MS pages and Neowin and simultaneously crashing both servers Just now finished the download of the 32bit version and getting 64bit as well to perhaps run on my other system (dualboot with XP there). Got all 10 (!) keys they're giving out noted down. Both my Live IDs gave one of those ten, so the concensus is they lifted the 2.5 million limit and made it free-for-all.
Anyway, I love every bit of it. It not only looks better, but unlike Vista it actually makes getting stuff done easier and faster. After a month of use I've come to a list of 5 very minor glitches that I'll be reporting after a reinstall and activation. So I'm just very happy the beta is so stable that I can just leave XP and Vista behind
