Hello There, Logitech Anywhere MX'm the very happy now since 1.5 months and am. She worked for me out-of-the-box in Windows 7 and Ubuntu 10.04 to 100%. The workmanship is very good, in terms of weight you can operate the mouse with 2 AA batteries, making it a little harder. When it is, however, operates only with a battery not heavier than other notebook mice. The ergonomics is better than expected, as it is not in proportion to the length too high. The sampling is, as advertised by Logitech, on all surfaces with extreme precision. Battery Life: I use the mouse daily for 1.5 months and in SetPoint 4.80H a residual maturity of 90Tagen appears. Only the regular clicks and you can not use it as a middle mouse button, the scroll wheel are noticed negatively. When you press the scroll wheel, you can switch between fast and normal scrolling. But the key to the scroll wheel can be defined as middle mouse button or is already set and defaults so.
Summary: Pro: + Ubuntu fit + Very good workmanship + Variable weight + Very good ergonomics + Extremely precise on all surfaces
Cons: - Somewhat loud mouse buttons - Scroll wheel can not be used as a middle mouse button
