I borrowed a NEX-6 and used it on vacation. The EVF is very good, video is decent, low light capability is good, panorama and built-in HDR good, an the 16-50mm kit lens is extremely compact. It is one of the few APS-C sensor cameras with a zoom lens that can stored in a purse or large pocket.
That said I didn't like it. The UI is extremely menu oriented, with the Setup menu having so many pages the scroll bar is just a tiny sliver. While I got pretty good results, it felt like a gadget not a camera. A number of NEX-6's have a "camera error" flaw which locks up the camera if the electronic front curtain shutter is used. It can only be fixed by returning it for service.
I have a NEX-6 and I agree the menu structure is not very user friendly. But still I think it is a pretty good and very pocketable camera with the kit lens! Despite the menu it is easy to use because the most important functions are directly accessible via buttons/scroll wheels. It's good to use with a 30 mm Sigma too. The biggest issue I have with this camera is the lack of good camera RAW editing software - I have to use Adobe Lightroom for the Sony and don't like it much, as well as problems I have with getting the color space of processed photo's correct (more of a Lightroom issue). If you want tele, the Sony E 55-210mm F4.5-6.3 OSS is inexpensive, very compact and nice to use, colors are good too but the resolution is only so-so. With the NEX-6 I can take a three lens system in a tiny bag. Very convenient.
My Sony NEX-6 'kit':
Sony E PZ 16-50mm F3.5-5.6 OSS
Sigma 30mm F2.8 EX DN
Sony E 55-210mm F4.5-6.3 OSS
What's missing is a macro lens, something this camera could be good at - but outside of my general interest.
