Hi Matt,

It's not the Arc Touch but this one: http://www.microsoft.com/hardware/en-us/products/touch-mouse/microsite/

It looks like the scroll features are similar although you can scroll from anywhere on the surface of the Touch mouse. I've been trying to get used to it and I'm very happy it works with BIAB 2012 now but so far I really can't say I like it all that much and I don't think I'd recommend buying one. I've got the scrolling down OK and the multiple finger gestures are pretty useful with Windows 7 but the precision of the mouse pointer just doesn't seem to be anywhere near as good as other mice I've used when trying to move the mouse pointer to a small link or button. Maybe it's just that I'm getting too old to learn new tricks...
