I use a Kinesis Advantage LF (Cherry Red switches) at home and work and it's a complete dream. I really recommend it to anyone, especially programmers, though it is pretty expensive. Your coworkers will probably make fun of you though. Before that, I used an Apple keyboard, and it gave me continuous RSI symptoms. The ability to hardware remap all the keys is nice too. I doubt I'll ever use a non-ergonomic keyboard again.
