@Jaffa - I'm a Nikon girl. What are you shooting with? I'm actually considering moving down to a 4/3 system. I've been reading reviews and studies people have done. If I take my full system into a place, I'm more likely to be harassed by security because they think I'm a professional. However, if I take a 4/3 system in (it looks like a point-and-shoot but has interchangeable lenses) they think I'm a tourist and leave me alone. People have tested this theory and it's true. Anyways, have you considered one of the newer/smaller cameras?
@McTattie - they're small because my name is watermarked across the middle of them and I don't want to share my real name on here. You can't see the watermark because it's so small.
