I get frustrated with the track pads. Sometimes they click, sometimes they drag, sometimes they right click. I know its number of fingers and pressure/speed of clicking? I'm sure it's great if you learn it, but nobody else has adopted it.
Oh, and 2 programs side by side and you have to jump between menus of both of them for whatever reason. The whole "1 menu per desktop" is frustrating
