@Freggo,
Talk about stating the bleeding obvious, but you can't really stick a DSLR on the end of a phone. As often quoted, the best camera for the job is the camera you have with you. Given that we know smartphone cameras aren't fantastic right now, we can look at Google looking to improve this as a good thing, or we can be really arrogant and say we refuse to take a picture unless it's on a DSLR.
