This one slipped under our radar this week, but it's interesting nonetheless: Apple's filed for a "Magic Trackpad" trademark, which would seemingly indicate that there's a companion to the Magic Mouse in the works. That's all we know for now, but recall that John Gruber at Daring Fireball hinted that Apple was working on a "multi-touch trackpad gadget for desktop Macs" back in October just before the revised white MacBook was released. Obviously nothing's come of that yet, but it all seems to fit -- either that, or Apple's trademark attorneys are just trying to cover their bases. We'll see what happens.
