I run 1920X1200 on both my laptop and desktop at home and WC looks fine. You will definitely have problems with most of the wallpapers as the largest resolution I've ever seen here is 1600X1200. I get most of my wallpapers from the members gallery over at digitalblasphemy.com as he does widescreen renders of all of his work. As far as WB, I've only had problems with it on my laptop when I changed the DPI setting to anything above 96 DPI which is the default setting. With the setting at say 125 DPI there were problems with borders not matching up and all kinds of strange little problems, so I stick with 96 DPI and everything is fine. With DX I just don't use the themes, because they are never designed for resolutions I run, I just use the objects I like on the screen somewhere..
