Great novelty value but doesn't work so well with Windows 8.
8 May 2012
Summary: I bought this primarily to use with Windows 8 running on a Mac. The touch reaction time is good but there's an issue where you can't activate the corners or side like you can with a mouse. This makes it a real problem with Windows 8 toggling between tiles and other areas. Then I discovered after a long search that you can get drivers to make it Mac OS X compatible.
