Have you swapped your DSLR for a NEX 6 or 7?

Coming from a Nikon FE (an analogue SLR), I have really fallen in love with my Nex-7 (mostly using my old Nikon glass). The biggest plus, for me personally, is the quality of the EVF with the focus assistance features. My main gripes are the Video Button (now mostly fixed in the firmware), the low numbers of high quality E mount lenses and the mediocre AF.

I am currently, seriously thinking about getting a Nikon D600 as a "second" body for my Nikkors because it is full frame and the various reviews I've read indicate that the D600 is "better" in low light/high ISO situations.
