I'm just curious, and will help me with designing my site. Mine's at 1280x1024.
Try moving your (Win) taskbar to a vertical position, I stick mine on the right hand side. Takes a day or two to get used to, but well worth it as maximises vertical real estate, can read the names of your apps in the taskbar, and can read the date in the clock.1200x800. I prefered the old 1024xwhatever, though. And all the various task bars take up too much real estate either way.
Didn't realize google analytics shows that info. Good to know.Are you designing a site for web developers, or web users? If it's for web users, then I'd be designing at 1024 x 768, or better still stick google analytics on your site and see what the current users are running.
