The only issue I've had so far is a little lag on the touch track pad on my blue keyboard, and the fact that when I want to right click I literally need to go over to the furthest right corner of the touch pad to click; otherwise it left clicks.
I think the latter may have actually been done on purpose (I guess the idea was that right-clicking takes place less and it'd be more ergonomic to provide some clear separation between the two), but don't quote me on it.
