Also, anyone suffering from wrist pain, mine went away after I bought one of these for use in the office:

I don't have one at home (they aren't that good for games so I haven't bothered to change my home setup) but just using it for the 8 hrs in the office a day was enough to get rid of the constant pain. Take a little getting used to , but really the way your hands sit on the keyboard make more sense than twisting them in to sit properly on a flat keyboard.
