Steve Ballmer touts 500,000 Windows 8 downloads in less than 12 hours

We've already heard that quite a few of you have downloaded Windows 8 since the developer preview became available last night, and it looks like plenty of other folks have as well --- about 500,000 in the first 12 hours, to be specific. That's according to Microsoft CEO Steve Ballmer himself, who took to the stage at Build earlier today to dish that particular bit of news and recap the past two day's events. Hit the source link below for a video of the full keynote if you missed it (Ballmer's appearance is around the 2:32 mark).
