How does the ergonomics of this work? The intellectual part of writing code may be improved, but physically typing the code while on the couch can't be a good thing.
(Typed while laying in bed, in a way that would certainly screw up my wrists if I did this long term.)
I use Vim, both for writing code and as a chrome plugin, so I'm usually just hitting a few keys in normal mode, or whatever autocomplete tells me, with the occasional swipe at the trackpad. I've never had any wrist pain on the couch. My macbook air is pretty ancient but it's still super light so I can just prop it wherever.
Separate keyboard (a Kinesis) on legs slightly bent. I'll prop up the laptop keyboard (like right now) for brief typing, but I agree that'd suck for serious work.
