My old trusted thumb-operated Logitech Trackman Wheel broke down little over month ago. For my surprise I found out that Logitech had finally released a wireless version (Logitech Wireless Trackball M570). This mouse was a little more expensive than old modle but it also had two configurable buttons mainly for browsing purposes. Now, the mouse is just great. As a verdict I can’t see the difference to wired version. But what really struck me was how fast I adapted into using the extra buttons. Can’t live without ‘em anymore.
