I picked up a refurbished Surface 2 to play with since I have no experience with the Rt OS. It has RT 8.1. I also got a type cover on eBay, and now I'd like to get a mouse. MS has the ARC and Wedge mice, both are very small. I'd like a larger mouse for hand comfort, expect I'll have to go Bluetooth. Anybody have any suggestions, or experience in this area. ETA - Surface specs say it is Bluetooth 4.0 Low ETA2 - After looking around, I got one of these mice, it is not bad. Logitech - M557 Bluetooth Mouse - Dark Gray The Surface 2 arrived with a battery issue and is on its way back - still have mouse and type cover 2 - toys are fun.
