After being leaked a number of times in various ways, officially and unofficially, Microsoft’s Arc Touch Mouse (not Arc Mouse Touch, as previously suggested) is finally being given an official launch.
It’s got a Bluetrack sensor, a touchable strip instead of a scroll wheel (with haptic feedback), and you turn it on and off by cracking its back. They sent me one to check out, but for some reason I decided to write up the announcement separately. Head over here to read my hands-on impressions.
