Title: Better than Microsoft's, but still lacking
Review: Side by side (I have both at my desk right now) this mouse is hands down better than the wireless intellimouse explorer. HOWEVER, it does lose its mind once in awhile and jump across the screen. 1 month is about all you can expect the batteries to last. Big-handed people will find this thing a little small. The slope of the mouse puts your wrist and forearm at a funky angle.However, compared to the MS mouse...it (1) is not nearly as heavy (2)is better balanced (3) slides easier...which makes delicate pointing tasks easier (4) exhbits FAR less hysterisis (5) wakes up faster.One thing you will notice with almost all of the optical mice is their tendency to sleep on you as soon as you stop moving them. That fraction of a second that it takes them to wake up is enough to cause a "jump". I have yet to find a wireless optical mouse that does well for fine-positioning work found in graphic design tasks.
