Pity poor buttons. Once a symbol of cutting edge technology – see the excitement over push button phones in the 70s, or any Star Trek episode – these days it’s all about touchscreens. The latest slap in buttons’ face comes courtesy of Logitech, which has unveiled a touch mouse. The Logitech M600 ($70) provides full surface touch sensitivity, so you can have that smartphone feel when using your PC. We’ll have to get our mitts on one before we can say if it’s an improvement, but please excuse me while I go fondle my pants button before that disappears too.
