I run 3 x 1600 x 1200 LCD's together on my main desktop machine. I've owned them for over 5 years and keep a forth one spare just in case any 1 of the 3 goes "bang!" since they aren't manufactured any more and continuity is important to me
Prior to that I ran 1600 x 1200 on a single 22" CRT, which weighed a tonne and have now given to a relative, which I bought in early 2001.
I also have a laptop that runs 1920 x 1600 (UWXGA) and both my previous 2 main laptops, the first which I purchased at the end of 2001, both ran 1600 x 1200 natively (UXGA LCD's).
So whilst high resolutions are common these days, I wonder how many of you have been running 1600 x 1200 or higher for as long as I have.
