Summary: Unfortunately picking near the edges of the screen with your fingers is not good. So picking anything off the task bar is a non-starter. It simply does not place the pick near enough the edge. The touch screen is a supplement to your mouse, not a substitute for it like you have on an ipad. Of course your other choice is to increase the size of your icons and lose screen area for other things.
Great novelty value but doesn't work so well with Windows 8.

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.
