Pros: Easy to use. Highly versatile! Looks sweet!
Cons: Some of the gestures are not consistant. Not pressure sensitve
One of the things I'v e learned in the Apple store is 'look, but don't touch'. I know, I know that they actually encourage you to touch and touch a lot. The thing is once you touch it, you've got to have it and if there was ever a device you should keep your fingers off of, its this one. Once you run your fingers across this brushed aluminum slab, it is all over with. One finger, two fingers, three fingers, four! Pinch, swipe, back and forth, left to right, up and down!. Yes, it is technical porn. I don't even have a mouse anymore. Just my wired keyboard and this wireless wonder.
What gets me is that it looks so minimal and yet it is so highly functional in the Apple kind of way. In the same way the iPhone has wrecked me for other phones (more than one button now frightens and confuses me), the Apple Magic Trackpad has wrecked me for mice (mouses?). I love that it sits where it sits and you don't have to worry about running out of real estate like you can with a mouse I also like the size of it compared to the size of a trackpad on a laptop.
The only thing I don't care for is that sometimes it gets kinda jerky and that can be annoying and I don't know of a quick fix for that, not even a restart. Also it would be nice if the battery strength was more easily available in the menu bar like the Airplay menu.
