I have always used 2 monitors and still do - I tend to really prefer using the console view for almost everything, while using the track view for editing and not much else.
I've always preferred to have 1 screen dedicated to the console view and 1 screen dedicated to track view.
Personally, I've found the multidock and skylight interface a bit challenging / frustrating, likely because I haven't taken the time to get used to any benefits it may derive, but I always found the console & track views each on one screen as most comfortable for me.
