Just another suggestion, I have similar issues to you and I can't spend very long sitting at a desk. I also spend a lot of time on the computer and I like having a fast machine with a real keyboard and a decent size screen. I also like to be comfortable.
I sit in a leather reclining chair with the keyboard in my lap and the mouse on the arm of the chair, both wired for reliability and convenience. The screen is just above my feet when I'm lounging back.
