If you thought the new Get a Mac ads were spot-on or funny, then you will definitely get a kick out of this. On Microsoft's Photosynth website, they admit something that Mac users have known for years: They're not cool enough to run on Macs. "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. Trust us, as soon as we have a Mac version ready, it will be up and available on our site," reads the website. Photosynth is a technology Microsoft has designed to create 3-D "worlds" with your photos. PS Actually it's not quite accurate as some Windows emulators running on Intel Macs will in fact run the software, notably Fusion.
