The -400's have the same style cockpits as B-757/767, two "glass" screens on each side of the cockpit with the other flights instruments being analogue. The over head panels of every single B-737 are pretty much the same with very few differences. This is primarily because Southwest convinced Boeing to keep type commonality for the 737. You buy 1,000+ airplanes you get what you want. The -400's never really fully caught on because they added weight to the plane without adding any fuel so the range decreased. Boeing corrected that with the -800. Frankly, as 777ER said the planes are worth more as parts than complete airplanes. Not like there is a shortage of B-737 out there.
