I'm going to guess and say that in any given city a lot more IT specialists work from a fixed workplace all the time. Also I would guess that a big number of currently wandering IT specialists can switch to fixed workplace (e.g. - random cafeteria vs home/work place) but they currently don't want to for reasons unknown to me. For me, when I was working on laptop on a previous job I would switch to desktop with ergo keyboard and normal screens immediately if possible. Being impossible I just switched jobs - it was that important to me (after money of course).
