I don't buy into none of them fruity keyboards. I might start considering options like that, if I experienced any pains in my hands, wrists, or arms. But, once I switched to a good chair, I've never had any keyboard related pains (while I'd experienced tons of problems before that, and experimented with split keyboard layouts to no avail...one thing that did help, was switching to a tiled window manager and almost completely killing the mouse from my workflow). I guess everybody is different, but I'm perfectly content with a good quality traditional keyboard (though a shorter reach to escape is a nice feature).
