My job started the concept with giving everyone laptops and an external monitor. So much easier to review docs on one screen and keep e-mail and web on another, and makes editing better as well. When I built my personal rig some years ago I had to choose between one big (27" or better) rig or 2 21" panels. Ended up getting two AOC IPS monitors (which I ultimately want to put on VESA mounts) which have served me well. So much easier to have a video running full screen on one monitor while browsing on another. My wife switched jobs where they have dual monitor setups and now she wants a second monitor for her MBP...

One big screen would work better for gaming, but I don't do enough of that on my PC, and if I did need a big screen I have a HDMI cable run from the GPU to my flat screen, which works
