If you just want a solid general purpose mouse, get the Logitech Anywhere MX.

It's definitely one of the best travel mice we've used, and the fact that it has better trackability with Darkfield means you won't need to bring a mousepad along with you.

The bottom line: The Anywhere Mouse MX bears Logitech's multiconnective Unifying receiver and glass-tracking Darkfield laser, but $80 is too much for a portable mouse--especially when the Microsoft Wireless Mobile Mouse 4000 costs half the price for almost the same features.

The Logitech Anywhere Mouse MX is an attractive, effective and cleverly designed wireless mouse for use on the go. With plenty of innovative features and the ability to work on pretty much any surface, this product can warrant its relatively high price tag.

The largest drawbacks are the lack of wired operating and the imperfect gliding traits of our test unit. The very good overall impression remains almost undimmed and thus we can recommend the Anywhere MX as a mobile notebook mouse.

The Logitech Anywhere MX mouse is a winner. Its understated good looks and solid feature set make this a very capable everyday workhorse, at home, in the office, or on the road.

A few minor quirks aside, the Anywhere Mouse MX makes an excellent computing companion.
