A certain geek *coughColecough* picked up an Ergodox some months back. After an initial period of smiling at his purchase while enjoying my work supplied ergonomic keyboard, I decided to take him up on his offer to type on it.
I can only say that in order to understand the draw of mechanical keyboards, you need to use one for an hour. They're pretty freaking cool. Sadly, the Ergodox is a bit out of my price range at the moment - saving up for a roadie while training for a triathalon next year. I also borrowed a Code keyboard using Cherry MX Clears, but decided I liked the ergonomics of the Dox.
Here's where the Atreus comes in. It's a 40% keyboard, so only has 42 keys instead of the 87/104 "normal" keyboards have. All the extra (punctuation, numeric, function) keys are accessed by switching "layers" - essentially shift on steroids. Jump in after the break!
