Letterbox is a plugin for Apple's Mail.app that takes advantage of your widescreen monitor. It rearranges the interface into three vertical columns --so the message pane is to the right of the message list, rather than below.
I just installed this, and it's pretty darn good - like "I can't believe Apple didn't come up with this" good. Go check it out!
