I picked one of these up a couple weeks ago when my laptop touchpad buttons stopped working reliably. One thing to keep in mind is that it's pretty damn small. This (and the stow-away USB receiver) makes it very nice to pack in a laptop bag, but it takes quite a bit of getting used to. I regularly find that my middle finger is resting on the central "scroll panel" which results in unexpected scroll-ups.
Also, for those still trying to figure out how it works from just the pictures, the scroll panel itself doesn't move, nor does the whole "panel" detect your fingers movement. There are 4 arrows on the panel, and when you "flick" them, it scrolls.
It takes some getting used to, but then so did migrating from the old thinkPad touchstick to the new(er) touchpads.
