Am I the only person who has and uses a 1600x1200 monitor? People and their widescreen! ;)
I actually got a 4:3 monitor on purpose though, since at the time, big widescreen monitors were too expensive and I wasn't willing to settle for fewer vertical pixels (for programming, height is more important than width for me) and I didn't want the hassle of flipping a widescreen monitor sideways.
