Hello guys, I've used the Logitech Trackman Optical Cordless until it broke on me, it work very well and I loved it. Using a regular mouse, even the ergonomic MX 1100 causes me great wrist pain. I plan on buying another Logitech Trackman, but I am just wondering if you guys know whether Logitech may ever come out with a new and better version? I think a small bluetooth receiver and a tilt scroll wheel, perhaps an extra button would make the optical cordless Trackman a trackball to DIE for! I don't know where else to ask but here, so thanks!
