While I was at the Eleutian offices last week I was impressed at their commitment to the multi-monitor lifestyle. I'm all about the Third Monitor (in case you haven't heard, it's one better than just two monitors) as are others. If you value your time, you should think about getting the widest view possible.
The Dell 30-inch is amazing...they each had a Dell 30" widescreen at 2560x1600 pixels, but they also had what appeared to be two 22" widescreen's also, rotated and butted up against the 30" so their horizontal working space was 1050+2560+1050=4660 pixels wide. Glorious. I turned them on to (I hope) RealtimeSoft's must-have Ultramon multimonitor tool. They were running x64, and Ultramon has a 64-bit version, so that was cool.
I have a 22" Dell, so I might get another, plus the 30" to achieve this orientation when we build the Ultimate Developer Rig.
A few days later, I hung out with John Lam some, and while we were driving somewhere, mentioned that he'd taken an Advanced Driving Class with BMW and recommended to anyone, even folks without German Cars. (I drive a little Prius, by the way, and intend to until it dies by the side of the road, at which point I'll get out and continue on walking...)
He said that one of the greatest driving tips they shared that he swears by is radically (to me at least) readjusting your rear view mirror on your cars to completely remove blind spots.
I'm used to turning my whole head (and body) to look to the left or right when changing lanes. We were taught that the way to adjust your rearview mirrors was to make the side of your car just barely visible in the rearview mirror. I've always taken that orientation of mirrors for granted.
Typical rear-view mirror configuration looks something like this (please forgive the Paint.NET-ness of this rough non-vector sketch):
There's a great deal of duplication/overlap between what is seen in the main mirror versus what's in the side-mirrors.
The idea is:
Apparently amongst car enthusiasts a well-adjusted rear-view mirror is a known deal, but it sure turned my life upside-down. It takes a while to get used to, but when you're adjusted correctly, you literally have no blind spots.
Bringing it all back home, this of course, applies to multiple monitors, IMHO. Why not fill your field of vision with as much information as possible...otherwise what might you be missing?
