Are you one of those people who hates touchpads..or just prefers the precision of a mouse so you end up adding a mouse to your laptop bag. Trouble is most portable mice are kind of chunky and you have to give up some cool gestures available on touchpads. Well Logitech has you covered. The Logitech Ultrathin Touch Mouse takes it design cues from the wedge shape of most Ultrabooks Brushed aluminum around the edges and black on top and bottom (white in the Mac version). The top is a smooth touch surface. It uses Bluetooth with Logitech Easy-Switch Technology to let you connect wirelessly to your laptop, desktop or tablet at the same time, and you can easily switch among them with the flip of a switch. The Ultrathin’s battery is charged through a micro USB jack and just one minute of charge time gives an hour of use. I tested the Ultrathin on a MacBook air. No difficulty pairing via Bluetooth and once connected the OS X control panel allows for all the basic mouse functions. However install the Logitech Preference Manager app and a whole new dimension is added to the mouse in the form of a bunch of available multi-touch gestures. I found they all worked smoothly with no problems. I also tried it on Windows 8.1 with similar results. The multi-touch features and the silky smooth surface really makes working with the Windows 8.1 tiled interface a breeze The Ultrathin is small, at its broadest points, measures 3.25 inches in length, 2.25 inches in width and 0.5 inches in depth, though that tapers significantly towards the front end. It tips the scales at a featherweight 2.4 oz. It complements the look of my MacBook Air. I actually prefer the black model to the white one. The size is one niggle I have with this cool mouse. You don’t move it with your hand but rather you move it around with your fingers so it is not as comfortable as Logitech’s bigger ergonomically shaped mice. It is perfect for light use on the road but I wouldn’t be comfortable using it for long hours on a desktop. The Logitech Ultrathin Touch Mouse is available for Mac and PC for $70. You can order it direct from Logitech and it is starting to turn up on the shelves at Best Buy and Future Shop and other places Logitech products are sold.
