nice mouse if you like to exercise. me I can't stand a mouse you have to move all over your desk the pick up and move part of mice drive me nuts and no i do not want to speed up the mouse movements..horrible for photoshop work. I will stick with my trackballs as i find i have more control over my work this way. i have spent upwards of hundreds of dollars on mice. Wired, wireless, optical...etc etc all have issues. once I moved to the trackball line of mice I was floored. takes about a good week to get use to a trackball, maybe we will see soon a laser trackball and i will have the best of all worlds.

Nice right up my friend I pointed it to a Doctor friend of mine who was in the market for anew mouse. he ran out and bought one later that day
