Anyone returning their RX-1?

Hello,

Wouldn't your NEX5N or DLSR kits be more versatile for your professional paid assignments because of interchangeable lenses whereas the RX1 would be limited because it's a fixed lens camera?

Or do you tend to carry more than one camera with you?  So carrying a combo of either NEX5N, DSLR, and/or  the RX1 would seem to cover all your bases.

Regards.
