FWIW I have a fairly wacky keyboard (36-key Corne) that uses lots of clever layering to hit different symbols. It took a bit to learn as my daily driver but 1) it's awesome to have all your keys so accessible to the home row, and 2) I haven't experienced any degradation in my muscle memory of normal keyboards, and I only use a normal keyboard (like my MBP) maybe a few times per month.
