I'm just curious. Some of you take ginormous digital pictures for example. The real reason though, is that I just got a new monitor at work, it's a 17" LCD with a native resolution of 1280x1024. I've been using 1024x768 for years, my 15" LCD at home limits me to that actually.
I tried to set the resolution to 1024 on the new 17, but due to the nature of LCDs, it looks like garbage, so I just keep it at 1280. I've noticed since having that new monitor, that very few internet sites utilize that much screen space. Most sites seem optimized for 1024 or 800x600.
