The nice thing about the widescreen is that it fits multiple emacs windows side-by-side, so that you can view substantial portions of more than one buffer at once (or two substantial portions of the same buffer). That said, the first rule of screen space is to have more of it. Whether or not it's optimally distributed is secondary. In web development there is always a use for more windows. (Docs, server logs, logins under multiple identities, multiple browsers pointing to the same thing for design debugging, IRC...)
