If you keep this up though, your wrists, neck, and back will make you pay for it in a few years.
I have been doing that for years as a nomad of sorts, but it kills your back. I recently bought a small keyboard so I can get a better posture and I recommend you so the same.
Hmm, I might do that. It's been a year since I ditched my desk. Though my 16" MBP screen is big enough that it feels almost like a desk monitor.
