And here's another thing. I've lost count of how many desks I've seen where people have got all bent out of shape over getting this or that ergo keyboard and wrist rests and foot rests and all the rest of it, but they point with the most utterly shitty godawful mouse with the buttons in the wrong place and a ratchety, gritty-sounding wheel, that doesn't track with any degree of accuracy.
I draw a lot of things (used to be AutoCAD, now I've "graduated" to Visio - bid work again...) at work and a good pointing device is paramount.
At home and work I use a Razer Deathadder (stupid name, great mouse) because it's got high quality furniture, is properly left-handed, and tracks very precisely. At home, this is important because I do two primary things on my PC: edit photos and play games. Both of which reward a good Pointer-o-Matic.
ETA: How noisy is that Logitech? Ah, no matter. Just googled it. No keypad. Dealbreaker. Also, 90 quid is a lot of scratch for a keyboard.
