Do you have one of these?  I got mine several weeks ago and absolutely, completely adore it.  The studios at have them and, while there, I always play on their wonderful MAC computers and on the Wacom tablets.  It is so much easier than a mouse and a seriously cool invention.  I haven’t done a lot of photo editing with it (which is when it’s really amazing) but have just been using it as my "mouse" and getting the feel of it. 

I ordered a refurbished one off of the Wacom site – and not looking back!  If you dislike the mouse, want something easy on the wrist and have a little more room on your desk (the "footprint" of mine is about 8×8") then hurry and get one today!
