I prefer 4:3 as well, you get plenty of space, and if you can afford two, the better. Manufacturers are pushing wide screen panels because they're cheaper to make, but, objectively speaking, none of the so called pluses are actually that, like for example, that you get a bigger screen (LOL) or a 16:9 screen feels more natural for reading (of course, go to those sites that expand the layout to fill all the screen, like NeoGAF, to see how nice and natural feels reading something like that).
On the other hand, what João comments, having two files side by side, it's a big plus, and a true one, not mentioned too often.
