Looks like a Kinesis Advantage. I've long been tempted to get one, but could never convince myself that it was worth $300.

Seems to me that the recent Microsoft keyboards are kind of mushy. I use an Apple wireless keyboard at work. It has a relatively light touch, and is comfortable on my lap. At home, I'm breaking in a tenkeyless keyboard with Cherry MX Brown switches. There's something satisfying about banging away on it. I bet the Blue switches would be even better, but I was afraid they'd make too much of a racket.

I've gotten a bit of WASD claw from first-person shooters, gorilla arm from poor mousing form, and gamer thumb from too much Xbox. Those injuries (if I can even call them that) didn't prompt me to search for a new keyboard or an ergonomic game controller. I just backed off a bit on the offending activity.

Ergonomic devices would help, but you are wise to back off a bit on those activities. To me a dream keyboard would be Microsoft 4000 with softer keys, and most importantly, with the number pad split.
