I don't know any review sites, but I can tell you that I'm very happy with our new Dell Latitude D800. I get a little over 6.5 hours of life with both batteries, reasonable size (although a tad large), built-in wifi, and a pretty comfortable keyboard (to me anyway.) With it being a widescreen, I also like the ability to put two page size documents side by side, and the extra desktop real estate.
