My MacBook is the white model before the unibodies came out. In fact, it missed being a unibody by only 6 or 7 months. This means that, being an EARLY 2009 MacBook, It doesn't have a 3 finger plus trackpad. That's why I want a magic trackpad, so I can get gestures. I know it's kind of a lot, so I thought I'd pick up a used one on eBay or something. My question ~> How well does a MT work with non unibody Macs?
