Ergodox looks damn enticing.
But I'm not planning to switch because it will make me unlearn all the traditional keyboards for me. In particular, I will have trouble touch-typing on a laptop keyboard after that, and there are zero options for an Ergodox-like layout on a commercially available laptop. So, no way to work on a train or a plane.
I wish some laptop maker were so brave as to offer a split and angled keyboard as an option on a laptop with decent internals, though.
