The position of the screen is important, and it's a lot easier to position correctly a 27 inch monitor than a 13 inch laptop. A properly fitting chair and desk, ergonomic keyboard and mouse, all of this can make a noticeable difference, I promise. About four years ago I started to have some mild wrist and lower back discomfort, especially after working long hours... I decided to improve my work setup because that was the easiest thing to fix without changing my habits. Since then all discomfort was gone and haven't had any issues even though I still spend way too many hours on the computer. I know I should still change my habits, especially since I'm starting to notice I don't feel quite as young any more, but don't discount the difference a good desk setup and posture can make.
