I a month or so ago I bought a monitor from some guy on craigslist so I could run my raspberry pi more easily. After using it a few times I looked at my main computer and thought, "Why not go with a double screen when I'm not using the pi?"
I mean, what kind of computer geek doesn't have a dual monitor setup?
I. Am. Hooked.
Now I'm trying to talk my wife into letting me put a larger computer desk here so I can go with a 3 monitor on the desk and an extra wide monitor spanning over the 3 on the wall. That sounds reasonable.
