Either Dilbert has a really long keyboard or his second monitor is a laptop, and he's kickin' it oldschool with Synergy instead of using a recent graphics card.
In celebration of Dilbert, I'm running a quadscreen rig today (synergy'd in a dualscreened laptop) instead of the normal dualscreens. One time I added *two* dualscreened laptops, and my whole desk was monitor. This is a spacious home office too, btw...
My office all got dual monitors last year, you do get a little ego boost seeing the rest of the staff still toiling away on one, that is until you go into IT and see the helpdesk guys with the 6 screen rigs....
