"Fantastic design, ease of use"5.0 starson by drdunkyn
Pros: The real beauty of this mouse, aside from its sleek outward appearance, is in its multitouch potential -- using a great app like BetterTouchTool, gestures can be added to replicate functions of MBP trackpads. And it works almost perfectly.
Cons: The lack of built-in support for any gesturing beyond basic scrolling/flipping (which, though cool and useful, is too limited). This has already been corrected, though, by 3rd party software.
Summary: This mouse essentially replicates the functionality of the trackpads on the MBP's, which I have grown to love and find indispensable in working with photos, and movies. The interface feels natural (if you are holding it correctly), and once implemented with the BTT app, gestures enabling up to 23 discrete movements( including 1, 2, and 3 finger touch, click and swipe, as well as pinch to zoom) are now capable of being assigned, in the same way as can be used with the trackpad. Will everyone like it? Of course not. But for people such as myself who have enjoyed the superior multitouch interface that the recent Mac laptops utilize, this will be the perfect addition to a desktop setup. It's not going to cause carpal tunnel, or give you cancer...but naturally, try it first before you buy it to see if it suits your needs.
