Looking to do nothing less than redefine the mouse, the Logitech Cube packs extra features into a tiny, shirt-pocket-sized package. So what does it do? Well, it’s first of all a wireless, optical mouse, with Logitech Flow Scroll that lets you scroll pages by sliding your finger, just the way you can on a smartphone. Next, pick it up and it’s in presentation mode, controlling a slideshow, one frame at a time. Under the hood, there’s a tiny Logitech Unifying receiver that turns this mouse into a wireless hub, connecting up to six Unifying-compatible devices within 25m. In there also, a long-lasting, USB-rechargeable lithium-polymer battery, with low battery light. And there is an On/Off switch.
