Sounds like you need a Latitude C400. Best laptop I ever owned for portability, toughness (Titanium LCD cover), and great looks too. Not to mention, with a 1.2 GHz mobile pentium and a gig of ram, it holds it's own with business apps. 12" XGA resolution (1024 x 768 native) screen and a decent size keyboard. Most come with integrated wireless and IIRC a single USB port. You can pick them up all day long on ebay, and most are well within your price requirements. Good luck!
