You have to give it to Microsoft for having a sense of humor.  Whilst browsing the Microsoft Photosynth site on my Mac at work, you are presented with this text:  “Unfortunately, we’re not cool enough to run on your OS yet. We really wish we had a version of Photosynth that worked cross platform, but for now it only runs on Windows.”

Nice one Microsoft:

On a side note, I really wished you didn’t have to use Jerry Seinfeld in your response to Apples “Get a Mac” campaign. Ricky Gervais would have been a far better alternative.
