It was my birthday t'other day, so I treated myself to a new mouse. For the last 6-7 years I've been using a Microsoft Optical Intellimouse, one of the first optical mice they did. It was brilliant, well shaped and reliable - I only had to get rid because it was getting old and randomly double-clicking. My favourite feature was a simple one - the fourth and fifth buttons were on either side of the mouse. It was still quite ergonomic, and made for some very intuitive "leaning" keys in what was my online FPS of choice at the time, Soldier of Fortune II. When I originally considered an upgrade a couple of years back I noticed Logitech doing a wireless gaming mouse that had a similar button layout (which is rare - most keep the extra buttons by your thumb), and an exceedingly clever power system. The wireless receiver was part of a USB charging station, and the mouse came with two batteries. One charged while the other was used, and the changover time, assuming one ran out in the middle of a game, was recorded at around five seconds. Unfortunately they were a tad expensive at Â£50-60 back when I was a student so I never got one. Now I've finally got around to buying a new one, I've been unable to locate the mouse I wanted. Apparently Logitech discontinued them and I can find no reference to them anywhere. Instead, I've settled for a Logitech G9x (less than Â£70 on Amazon, not the Â£90 advertised). As you'll see from the specs, it's pretty nifty. I've had it plugged in for all of ten minutes just running across my desktop and I'm already impressed. The on-the-fly DPI changes make quite a difference, and both interchangeable grips are easy to swap, comfortable and well-designed. I'm "working from home" tomorrow so will get to give it a proper road-test on MW2 to see what difference it makes in the actual gaming. For the rest of my gaming, I have another Logitech wonder for my keyboard - the UltraX. Again it's been discontinued, but essentially it's a full size, yet slimline, almost laptopesque keyboard. Very comfy indeed, in games but definitely for typing. Sound-system is Logitech again (not through and love of Logitech, they simply seem to offer the best solution every time I need something). Full 5.1 Surround for under Â£70, crystal clear and very well made. Random extras on the desk include a cheap Tesco halogen desk-lamp (enough to light my keyboard without needing the main light on), and a USB fan that I got for Christmas. It's not had much use, what with all the snow, but imagine it will come summer! They all plug into a very useful multipoint surge-protected power adaptor with four plugs, a USB-hub, ethernet hub and phone hub built in - and it all sits on a Â£50 Ikea desk that is surprisingly good.
