The Anywhere 2 trades the Master's auto-switching, dual-mode scroll wheel for a more traditional push-to-switch approach. It also ditches the horizontal scrolling wheel on its larger sibling. The mouse can still be switched between three paired devices, and its "Darkfield" laser sensor can track movement even on difficult surfaces like glass.
Owners can connect the Anywhere 2 to Bluetooth Smart-compatible devices, or they can use Logitech's own Unifying USB receiver. The LiPo battery is said to last for as long as two months on a charge. Look for the mobile mouse in stores soon at a suggested price of $79.99.
