I have a tiny second monitor, a square one (15" I think), nd I found it very handy for having charts and things (sometimes a manual/tutorial). I appreciate the handiness of a second monitor, but I can only guess what having half a dozen are like! Awesome I would reckon. Unfortunately the power lead to that second monitor is loose fitting in the socket and the monitor was shutting off randomly, so at the moment it is not connected. One day I'll get around to replace the lead and get it working again.
