alt Hacker NewsGlove80 is super nice, though rather expensive.
I got one with low-force switches. It's very comfortable to type on, but between the low-force switches and slightly different layout from a regular keyboard (column-staggered, concave, symbols in different locations) I make more mistakes. So I usually type on my laptop instead, especially while coding.
If you are comfortable using the laptop keyboard what was your motivation to buy the glove80? I use that as my daily driver but if I didn't get tendonitis from normal keyboards then I wouldn't have bought it.
