Not at all, for me, I only have a laptop and that monitor that sits on it.I tried 2 and 3 monitors and it made me more confused than productive, but I guess I'm used to tab around. Chat And email I get notifications about, so no need for a monitor and my focus is only one point at a time anyway.
Now I've a 15 inch laptop with 4k, that's nice, but before I had 13 inch with less than full HD, that's a bit too tiny.
