I personally only use my Macbook Air unplugged for 90% of work which includes a lot of typing and reading. This works fine for me because the vast majority of the time I'm not on my desk - sometimes I'm on the couch next to the catering area, sometimes I'm on the bench on the balcony outside, sometimes I'm in a meeting room, sometimes I'm at a cafe outside, etc and I move around all the time. IMHO, moving often and taking stretch breaks trumps any benefits you would get from a fancy ergonomic setup.
