I almost always use a split keyboard when I'm able to set up a stationary environment. But I love to go mobile: coffee shops, beaches, couch, bar counters. I never forget how to use a normal keyboard, nor do I lose any speed. That might be the trick, maybe you need to switch between the two occasionally.
I have this crazy plan to create a harness where the two keyboard halves hang on the sides of your body (think sitting or standing with your arms naturally hanging down - the keyboards will be positioned under your palms).
But I'm still not sure if it would be too cyborg-y enough to use in public...
HAHA! Could be just sewn into your pants. Then you could just walk around the hood wearing some AR goggles while you work. Doesn't solve the tendency for your arms to swing in the opposite direction of you legs though.
I've had the exact same idea. I would love to not be constrained to having to sit down infront of a screen. My dream setup would be a projector-screen on the wall and being able to walk freely around while coding.
