Hey, I just bought a Canon S5 for 399 and was wondering if I wasn't better off just returning it and getting a Nikon D40, for 80$ more. I played around a bit with my Canon S5 and to be honest, the pictures aren't THAT much better than with my old point and shoot. Can anyone tell me the differences out of the box? Would it be a good idea? I'm planning to do alot of pics and probably taking photography courses..
