waise you can go for double lens, because sometimes you want to cover a large area in picture but you cannt because ther is not much space to move back and cover maximum (this comes handy in crowded places).
Kodak V570 is one camera having this feature and I have used it. Its simply awesome in terms of results. It also has on camera digital filters (but wonnt suggest going for that if you are just an amateur)
