To everyone that took part in the Windows Vista beta test (as far as I know, about 20,000), only those that submitted at least 1 bug report will be offered a complimentary copy of Windows Vista Business or Ultimate.

Microsoft sent out a mail to those testers just a few minutes ago which specified that it is being offered as a download only. No media will be mailed, and only currently active, invited members of the Windows Vista technical beta program who filed at least one bug are receiving this offer.
