Anyone else who downloaded one of the beta or RC versions of Vista pre-release get a "Thank You" email from Microsoft? They're offering a buy-one-get-one-free deal on Windows Vista Ultimate. You buy a copy and they give you a second CD key. It's not really a useful thing to most people, because Ultimate is so expensive, but I thought it was kind of nice that they actually bothered to thank us betas (I'm one of the people who actually reported back to Microsoft , I know a lot of people just downloaded the betas to see what Vista would be like). But like I said... anyone else get one of these?
