I've only been using the keyboard at work for about a week and so far so good. I love that I can choose a "solid" color (instead of multiple colors) and change the color every day (Fn+Home) - I got a lot of comments about cool colors. The keys have the ideal distance from each other and are easy to press. My old MS keyboard at home makes me press the keys harder and so I make more typos. I don't have this problem with this keyboard. The only thing I miss are the calculator buttons. I also love mice. The only complaint is that sometimes my index finger doesn't automatically find the scroll wheel (it's sandwiched between two slightly higher ribs) and I have to look at the mouse to find it.
