May 21 - 1:15pm EDT   Logitech has announced a new mouse for notebooks, the V450 Nano. The mouse uses a laser sensor to achieve greater precision than optical mice, and like other Nanos operates wirelessly, using a tiny 2.4GHz receiver that plugs into a notebook's USB 2.0 port. This receiver can also be stored inside the mouse, in order to prevent it from being knocked out of a notebook during travel. Controls include left and right buttons plus a scrollwheel. [full story]
