It's a nice keyboard. I've had one for about 18 months (with blue switches).
Feels great to type on. The build quality is high and the keyboard has a pleasantly weighty feel to it. The case has a minimal, simple design which I like. Easy to clean.
The only negative I've observed in 18 months of use is that some of the keys are starting to show signs of shininess (specifically, the oft-used space bar and left shift key, which I abuse).
