After months of wincing every time I open a jar or turn a doorknob, I broke down and got an Ultimate Hacking Keyboard so that I could set up a split keyboard with angled-out tenting.
So far it's mostly just showing me all the places that I use the wrong fingers when typing, but the build quality is great.
I'm most surprised by the fact that the mouse emulation is actually decent! I didn't expect it to be really usable but I'm finding myself not grabbing the mouse as often.
