- It's cordless - you can put it on the left or right or anywhere else. - You don't strictly need a mouse.

- I remember thinking the touch-surface on the magic moues was silly -but now I miss it when Idon't have it... and I actually suspect (won't know until I try) that the increased size of the new touchpad will be an important factor - you'll essentially be able to use a finger like a mouse on a pad - without needing to necessarily resposition very much - giving you veyr mouse-like behavior.
