Microsoft can't write operating systems, but they sure as hell can make mice. I love me some M$ft ergos, yes sir. Razer, on the other hand is known for making insanely accurate mice for gamers, with thousands of dots of resolution on their optical sensors. Here's a mouse they've worked on together.
The Habu has 2,000 dots of resolution per inch in its digital eye. The 16-bit optical sensor tracks movement up to 45 feet per second, or up to 20Gs of acceleration. also The feet are teflon, which isn't such a rare thing these days. And the 7 buttons can be programmed with up to 5 game profiles. Side bumpers can be swapped out for smaller and larger ones, to fit any hand. The Always-On mode gives it little latency. We think that means it never goes to sleep, like many gamers we know. And yes, it actually glows all crazy blue like that.
