I got one of these shortly after it became available in Europe, but have since reverted to my previous mouse.
The problem with the Microsoft Touch Mouse is that it is too heavy, and tends to adhere, or dig in, to the mousing surface, irrespective of whether it is a wooden desk, or a hard or cloth mouse mat.
As such, it is difficult to position the cursor with any accuracy - click/dragging is worse, as the nose tends to dip when the button is depressed - and moving the mouse is tiring on the wrist (a first for me).
It's not all bad: the touch-to-scroll function is a joy; responsive and accurate. Only for it, I'd have given up on the Touch Mouse sooner and, now that I have, I do miss the touch functions.
