I am going to be so angry if[0] this makes web devs start designing for grids that have to be 1300px wide to work. I don't fullscreen anything (too wide for the height, and too wide for the font size!), and while the majority of webpages look just fine in a ~600px wide browser window, possibly after right-scrolling to put the content column in the window, rarely does a day go by that I don't have to tear off a tab and widen it---not to make it look good, but to make it usable <i>at all</i>. Like that crappy Bump page posted here earlier today: if you view it in a narrow window, even if you right-scroll the window the content is sliced at window-width, with the page absolutely unusable at anything less than my full screen width. I don't know if there's anyone out there still on an 800x600 resolution, but there's a significant portion of the web that they actually can't use in any way. It doesn't have to be that way!<p>[0]Realistically, I know it's "when", but I'll stick with the denial a little longer.
