The new Magic Trackpad is the first Multi-Touch trackpad designed to work with your Mac desktop computer.
That’s a pretty blatant lie.
The FingerWorks iGesture pad was a multi-touch trackpad designed to work with Mac desktop computers (as well as Linux and Windows machines). You can still see some web pages about it at http://www.fingerworks.com/gesture_guide.html
I know this because I have one, purchased before Apple bought FingerWorks.
Since Apple bought the company that made the first multi-touch trackpad for the Mac, I think it’s a pretty safe bet that they know damn well that they’re lying.
