Importantly for users on the move, the Wireless Laser Mouse 6000 claims longer battery life than any comparable rodent in Microsoft's range - up to six months! Another feature is referred to on the front of the box as ‘snap-in and go', which initially had me thinking Microsoft had come up with its own, snappier (forgive the pun) version of ‘plug and play'; until I noticed the picture beside it, demonstrating what it actually meant. What it refers to is that the 6000 mouse has an indent that you can snap the USB dongle into for easy, convenient transport.
While there are other manufacturers who implement this in their wireless mice with dongles, many don't - but they all should. I cannot emphasize enough how convenient this feature is, especially as replacement RF dongles, unlike Bluetooth ones (where your computer doesn't already have it inbuilt), are difficult to acquire. If you've ever lost yours, or spent two hours hunting around for it, you'll know just what I mean.
Not only has Microsoft included this feature, but its implementation is among the best I have seen. Thankfully your dongle doesn't so much ‘snap' in, as smoothly press in, thanks to a thoughtful rubber coating that prevents it getting scratched. And though it doesn't quite sit flush with the underside of the mouse, it is held so securely that it doesn't really need to.
Best of all, inserting the dongle into its cradle automatically turns your mouse off, meaning you'll never waste the batteries. It's little touches like this that remind you that Microsoft is still up there with Logitech in the peripherals market.
As the name suggests, the Wireless Laser Mouse 6000 uses a Laser sensor, meaning that it should work on more reflective surfaces than Optically-endowed beasties. Other standard features include the four-way scroll wheel and the two common ‘back' and ‘forward' buttons above your right thumb. From which you'll probably have gathered that this mouse is purely for the right of hand. If you are a leftie - like I was once upon a time - you'll have to go for the ambidextrous Bluetooth 8000.
In terms of ergonomics, the 6000 feels very comfortable, though it favours palm-users. Personally, I do prefer the shapes of some of Logitech's mice or even the Steel Series Ikari Laser Mouse, but of course, this is very much a matter of individual taste and depends on how you hold your mouse, what you do with it, and the size of your hands.
