wide camera angles are great. It basically means you can fit more in the picture/frame without having to physically move, which is ideal if you're in a confined space or in a situation where you're not able to move any further backward in order to fit more in the picture frame. But for all those who are shooting in wide open spaces (if not lacking the will from sheer laziness) lacking the common sense, you can simply just move back a few metres and crop the top and bottom of the image down a little on the computer afterwards for the same kind of wide angle effect (potentially with less lens distortion too). But if an affordable wide viewing angle lens is what you need without having to shell out for 400 plus lens you might want to read on.
