People don’t use their computers just sitting at a desk anymore. With a laptop, you might find yourself surfing on the couch, sitting in one of those uncomfortable airport chairs waiting for a plane, or at the coffee shop. Microsoft has announced the Express Mouse, which will allow you to “mouse” where ever you find yourself. The Express Mouse has BlueTrack Technology™, which allows you to mouse on most every surface (except clear glass and mirrored surfaces). The mouse can be used right- or left-handed, and it has 3 customizable buttons. It uses USB, so you don’t have to worry about batteries. It’s only 2.5″ X 3.8″, so you can take it with you in your gear bag. Microsoft says it will be available in Flint Grey and Hibiscus Red in April, and Turf Green, Dahlia Pink, Ultramarine Blue and Coast Blue in June. The Microsoft Express Mouse will be $19.95.
