Image quality of NEX

Isn't the NEX camera some kind of going back to the past? I don't see too much IQ on any of the pogo sample I have seen. Tey look like the first digital cameras i used in 1995. Am I wrong on what I see?

I know users will jump at me, but I can't find really sharp photos. Somebody tell me where are they. I like the small footprint and would like to use the 5n with a 50 mm canon lens.
