I cant wait for the browser wars to subside in order for support for my graphics to come around. I just make a 640x480, 800x600 and 1024x768 versions of my pages when crispness is crucial. Seems tedious i know, but I build at the highest res I need and just re-export slices at different reses. It also helps to have a bad-ass programmer for a little brother so your site can determine which version to display.
