I first heard about Photosynth when I saw the video by David Pogue (click on the video entry below that says Photosynth).
Watch that. You’ll immediately understand what Photosynth is all about. It’s a really cool concept! But, unfortunately, it doesn’t work on Macs yet. If you go to their website and try to look at something while on Mac OS X, it will say: “We’re sorry, but Photosynth currently doesn’t run on your operating system. Please see our system requirements listed to the right.”
Apparently, it wasn’t always that boring message. According to TUAW it used to display a much more ironic explanation. I’ll just quote from their original post:
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 we’ve known for years: They’re not cool enough to run on Macs.
