Yesterday was a big day. We shipped betas for both Vista (the next gen Windows formerly known as Longhorn) and IE7 on XP. These events were a long time coming, so the party felt pretty good. Robert Scoble, Microsoft evangelist and Chief Blogging Officer (my title for him, not his), covered the event in his blog. I even managed to wind up in a photo being geeky.
