I would get the smallest laptop you can find with reasonable specs, and just get a 24" Dell (or 30" if you get one with a decent video card) display to hook it up to at your desk.

This is convenient because you can easily take it to meetings, vacations, etc. and have all your data, but most of the time you'll be hooked up to a big display and won't need to use the laptop as the primary screen.
