Basecamp is web-based. It works on anything. From reading the actual Apple profile, it looks like the advantages they're really touting are: * It's a little easier to use. * It has video chat (a $20 webcam + mic kit and skype do that) * Switching made them realize that they could use basecamp instead of expensive windows-based software. It's cool for 37signals to show it off and everything, but for Apple, it looks like they're stretching their benefits a lot.
