This is so nearly the perfect wireless keyboard. It's only let down by the stupid F keys - they're not in groups of 4 so you can't find one by touch alone, and even worse they're not clearly labelled. They have icons on them for the shortcuts they perform, but the actual key names (F1, F2 etc) are written above the keys in a small font, in dark blue writing on a black background. Some genious at Microsoft thought that would work.
The good stuff though - lovely to type on, looks very cool, no reception problems, lots of extra useful keys, it just has that one flaw. Ok I should have looked at the picture more closely before buying. Luckily it's just a second keyboard for me and I have a wired Razor keyboard for gaming. I couldn't use the Microsoft one for gaming because of the F keys. You've been warned.
