After now trying two different mice for my SP2, (Microsoft Arch Touch Mouse and the Logitech Ultrathin Touch T630), I was wondering if most SP2 owners are using some sort of mouse, or just the touch or stylus to navigate? I have found the Logitech mouse to be the definite winner between these two, but I'm sure there's other good choices out there. Have you Guys found any other mice better as far as small size and function?
