A Multi-touch Mouse?

GearLog has a quick blurb on Apple's new Bluetooth wireless Multi-Touch Mouse. The concept is great and it's amazing it hasn't been made already. No I don't own a Mac (though I do own an Apple IIe) but it's a done deal that an M$ version will emerge before long. I'm not big on wireless anything except Gamepads as far as input devices are concerned, but I'm sure Logitech will create a wired edition along with it's overpriced Uber Gamer Edition.
