Logitech MX 1100 is an excellent cordless mouse
This mouse is excellent, though quality control might be an issue. The mouse might be too large for some people, but I find the supportive curved shape pleasing. There are a good number of programmable buttons, and the hidden thumb button is an interesting idea. Unfortunately I went through a couple of mice that didn't work properly, either being completely DOA or having malfunctioning thumb buttons, but that may have been due to a temporary contamination of the supply chain with returned mice. The batteries seem to last a very long time, and though rechargeable would might be good, it's probably better to use your own rechargeables and recharger rather than relying on a mouse company to come up with a good solution. If there is anything not to like about this mouse it is the wireless receiver, which is pretty huge if you are using it for a laptop. Such a large mouse probably wasn't designed for portable use, though.****
