The gestures are far too weak. It is used as a MacBook or Magic Trackpad users to the beautiful gestures. The Magic Mouse does not support only very, very few. Can also understand I extent, but there are missing essential gestures, such as Mission Control. So I have every time an icon pull into the dock, or at least use the trackpad. That's not very productive. The mouse was meant only for very complex tasks in Photoshop or for quick navigation in Xcode, but without these gestures it takes longer than with trackpad. I still give four stars because I still insist hope Apple in OS 10.9 incorporates a few new gestures for trackpad and mouse.
In itself, I can consider this mouse without any friend. Of course it has its price, and the familiarization period is somewhat long, as this mouse has no noticeable buttons. But after that it works like almost everything from Apple - simple and intuitive.
