I think that more than anything... it really comes down to the type of clients you want to attract. There are some clients that are going to care about or judge you on the camera you carry... they are concerned with perception and looking the part. There are also clients that won't care.. clients that believe in the substance and will trust that you're using the right tool because you're a professional, regardless of size.
In terms of being hired for "gear"... I see that several have said that you're hired long before a couple sees the gear and that is true, but I think you're forgetting the fact that your next batch of clients is seeing you at that wedding. Obviously, that doesn't work for everyone, though. I know that Todd has publicly stated on a number of occasions that the friends of his clients don't always have the same tastes as his clients, so he's not really interested in impressing his client's friends... and that is fine. In my experience, though, our client's friends usually are pretty closely aligned with our clients and therefore we do want to impress them.... that being said, I don't think our clients care about the camera. I do, however, think there are some photographers here on this board (not gonna name names) who's work attracts people that are very into themselves.... they like nice things, high end things, expensive things... they buy these things not entirely for quality of them but for the statement it says about them to other people. I think that if you have these type of clients and they are your bread and butter, then you better have the right gear, especially if their friends are the same way and that's who you want to impress.
