Interesting. I've always worked from a laptop (first a 13" now a 15"). I got to use a 27" Apple display earlier this year for 1 week. I found it hard to get used to. With a bigger display keeping the light from reflecting off it was more difficult, I had to move the mouse so much further to do things, and I physical had to move my head to view the different areas of the screen (whereas with the laptop I can just move my eyes). Happy to be back with the laptop.
