Just a bit more vertical space (a few? a dozen? more lines of code per screen) vs slightly wider screen (better for movies, and games maybe). It may be nitpicking, I actually grew used to 16:9 aspect ratios and don't really mind it.

i find 16:9 allows me to comfortably fit a text editor (with tree browser, minimap, and 100 columns of text) on the left and a terminal on the right. i need to shrink the text further than is comfortable for me if i want that layout on most 3:2 displays.
