At work, my workstation has a 17" monitor and I run it at 1280 X 1024. As for maximum resolutions, it really does depend on the monitor and graphics card you're using...and the drivers also make a big difference. Here at home, my 22" monitor on an old nVidia GeForce3 card ((yeah, gotta upgrade sometime)), seems to have different max resolutions every time nVidia release a new driver. While at the moment, I can set it to 1920x1440 using 56.64 drivers, the 56.65 drivers only had a max resolution of 1792x1344. It tends to jump around for some reason. Nonetheless, I run at 1600x1200 so it's no big deal and honestly, high resolutions only really matter ((for the hardcore)) in games.
