“The daddy of conventional mice that comes with something called BlueTrack that enables it function on just about any surface irrespective of texture, colour or albedo. Whatever the science behind BlueTrack's blue laser, it works. We tried in on a shiny white desktop that usually puts the kibosh on any laser mouse and it performed faultlessly. Power comes from a rechargeable AA battery, which can be replaced by a normal cell if circumstances dictate and you get two programmable function buttons. Though of no practical use, the base glows a lovely blue when you turn it on. In fact, we rather wish we could have had the blue glow on all the time, reduced battery life not withstanding. The scroll wheel could do with standing a little more proud of the device in order to make moving left and right across documents easier and the USB dongle doesn't lie flush when clipped into the underside of the mouse for storage – and that's the only way of turning the mouse off – but, ultimately, these are peripheral grumblings. Microsoft also supplies a mains charger, so you can top up the battery without having to turn your computer on”
Even with the blue glow I don’t think I will be switching from my Arc mouse just yet. Whenever you get it out on a train or in a coffee shop it is amazing how many people ask what it is (especially when folded up, and can’t believe it is a mouse. Now if they did a Bluetrack version which glowed on start up I could be tempted.
