1. NOT ergonomic. AT ALL. I thought knew how a mouse should feel...Until I put my palm around the MX Revo.
2. The trackball just stops working! This is a known issue. As dust builds up, you will need to take a damp cloth and clean the trackball periodically. Simply unacceptable for a $70 mouse.
3. Sometimes it's very annoying when I try right clicking and my finger is on the left side of the mouse.
4. Batteries. Not really a big deal for many, but I much rather prefer the option of simply docking the mouse when a charge is required.
