Hi everybody I own a SP2. While I like the type cover, the touchpad is very small...and almost useless (I come from a Mac and I feel the difference). I'd like to buy a bigger one with multigestures. What do you suggest? Are multigestures related to the driver (so that I can choose everry trouchpad I want, and I'll have multigestures)? 1) I found a Logitech touchpad, but is it possibile to have multigestures on it, ie.: 2 fingers, 3 fingers, etc...? 2) I just saw the type cover for the new SP3: the touchpad seems bigger, but is it possible to use it on my SP2? TNX!!!
