a 14" monitor is kind of small, but all in all I'd say the 14" one is a better laptop. open the "Build Yours" links in new tabs and click Tech Specs for each and compare. The baseline stuff for the 14" is better than the baseline stuff for the 15", which is what you'd expect since the price is higher. Another big difference is that the 14" has a built in webcam where the 15" does not, so that might be a dealbreaker if you really want an internal webcam.
