Not quite the same, but I had the option the beginning of this week between a Dell Latitude D600 @ 1.3GHz with 14.1" screen @ 1024x768, or a Latitude C640 @ 2GHz with a 14.1" screen @ 1400x1050.
Although I would have preferred the Centrino, the higher resolution of the C640 won it for me, at the expense of battery life and wireless.
I had the advantage also of seeing the 1400x1050 in person, as my boss has the same laptop. If you can go to BB or CC or a Dell stand somewhere, and have a look, you can see for yourself.
I would probably go for the 1920x1200 if i wanted things really small (like running 1600x1200 on a 17" CRT) or 1680x1050, but not 1280x800 though, that's too small
Confused
