I have a slightly different keyboard relationship; I used to browse the Typing Injury FAQ of alternative keyboard designs[1] and fell for the idea of chording keyboards and mobile devices like the DataEgg[2] (I still wonder if chording could be useful on multitouch mobile devices), then for mechanical IBM Model M, then for split Microsoft Natural, then if you're going to split for each hand, don't half-arse it, whole-arse it with the DataHand[3] and its opto-magnetic switches. Then why not type faster like a court reporter, with Stenography and keyboards which support n-key rollover so they can be used with Plover[4].
Actually, what I most like is a flat keyboard with full keys and arrows and separate F keys and numeric keypad. Because most of what I'm doing is not entering long-form English literature, it's text and key combinations and numbers and arrows and symbols and mouse clicks and holding a phone and anything which requires the concentration of a weird entry system, or needs both hands in just the right places, or cuts out lots of keys to look stylish or take up less desk space or squash keys together to fit on a laptop, or change the alignment of keys weirdly, or assume everyone has prehensile thumbs which can take 90% of the key load on their own, or disregard years of muscle memory for a little temporary fashion, are ... worse.
