Are you super-jealous of owners of new MacBooks, what with their fancy multi-touch trackpads? I mean, look at them, swiping with four fingers to do this and pinching with two fingers to do that. They think they're so great! Well, now you can join in on the fun with an add-on trackpad designed for multi-touch gestures.
For $50, you get Diatec's USB mini-pad, which is essentially an external trackpad that lets you swipe, pinch and rotate to your heart's content. It'll at least tide you over until you save up enough scratch for a computer with the functionality built in.
