Logitech has just announced the Cube. It’s a powerful mouse that connects with your computer (PC and Mac) via the included Unifying Receiver, which features Logitech Advanced 2.4 GHz connectivity with the “reliability of a cord with the convenience of wireless, along with the option to connect up to six compatible devices.” The Cube mouse is small enough to fit in the palm of your hand or in a pocket. It has a rechargeable battery and an off switch so you don’t waste battery when you don’t need it. Using Logitech’s Flow Scroll software, stroke your finger along the top panel and you’ll experience smooth, continuous scrolling that’s similar to scrolling on a touchscreen smartphone. It also functions as a presenter. Just lift it into the air and wait a moment while it switches modes, then you can advance slides by simply “clicking” the top of the mouse. When you need to go back, turn the Cube over, then click again. It’s available online only for $69.99 at Logitech.
