In summary, I like the capabilities of the NX1000 with better picture quality and lens flexibility, but the GC120 with Android is so much of a killer app for my needs that it is keeping me from pulling the trigger on either one.
Here's what I do:
I photograph cars for my website (edited due to advertising), in 4 main scenarios:
1. Photographing a car during a review: I control the whole scene, lighting, etc., no need for instant upload or sharing here. My current point and click typically does fine.
2. Photographing during an auto show: Scene and lighting is controlled by manufacturers and is almost always difficult to fight with. Instant upload via Dropbox or Picasa is desired for one of my writers to pick up the pictures to include in articles. Instant sharing on Facebook, Twitter, and Google+ would be a huge plus.
3. Photographing during an auto show unveiling: Scene and lighting is controlled by manufacturers and I'm competing with 300 other photographers at the same time. Instant sharing via Facebook, Twitter, Google+ is critical. Instant upload to Dropbox and Picasa desired. This is a situation where I snap a shot an immediately post it to one of the social media sites.
4. Photographing during a car cruise: Almost always outside, but typically in late afternoon to evening lighting. Instant sharing via Facebook, Twitter, Google+ would be nice.
I have a wifi hot spot on my phone to give me the connectivity I need for these cameras, I would not buy a data plan for the GC120.
What I really really want is something along the lines of the NX1000 but running Android OS. Is there anything like that coming or should I just buy one of the current models? If I go with a current model, will the GC120 be of sufficient picture quality and will I regret not having the interchangeable lenses.?
