It depends on what work I’m doing - in the office I have a 32” and two 19”’s, when I’m remoting I use my T420 which has a 14” (I think). If I need to tail logs or remote onto a few servers the extra real estate is invaluable, if I have a coding or SQL-script-writing task it doesn’t make a difference. It might even help having a single small screen by removing obvious distractions e.g. emails I don’t need to read, IRC messages.
