Oh, absolutely, the NX1 is technically miles ahead of the Galaxy NX. So is the NX500. The Galaxy is slow as heck and to restart it from idle is glacial. It's hard to change settings quickly and there are no dedicated function buttons that can be programmed. It has a beautiful grip and great screen and awesome Bluetooth transfer. But most everything else about it almost sucks compared to newer cameras and I would imagine the NX1 as well, which is classes ahead technically. But I'll be darned if some of my most breathtaking images didn't come from the Galaxy NX (breataking to me that is not sure if others would agree, I'm probably just a mediocre photographer). And I own a Ricoh GR and GXR, Fuji Xf10, Fuji Xpro 1, Panasonic G9 and GM1. All with a variety of lenses and lensors. And more Samsung NXs. I was soooo close to selling the Galaxy NX a few times but then comparing it to my NX500, I can't deny that the Galaxy just beats it, at least in Jpeg output. There is a 3D thing in there I just cannot achieve with my NX500.
But you have to go with your gut, and if having sold the Galaxy NX feels good, you did the right thing. I sold my Pentax gear even though my models and lenses were praised as standout cult items. I just didn't feel it. I think the beauty is that there are cameras out there that hit the right spot for different people. I personally can't do Nikon, their color science and rendering just does not gel with me. It's very likely brilliant but I cannot personally see the wow factor.
I will have to get my hands on an NX1. I hear the output is very comparable to the NX500, but maybe there's some fairy dust in there I'm not aware of.
