Photography: Camera sensor size difference

that is only really an issue if it prevents you from handing something to your client that you are not happy with or the the piece of equipment is overpriced compared to the competition.
any other issues are for forum fanboys with a flickr account to discuss.

Yeah - that's why I said I wasn't gonna start that argument. It's what you do with it that counts. Just like bikes, doesn't matter what you ride, it's about how fast you can make the fucker go.
