I think these cameras are brilliant for Sony, and they deserve credit for both pushing the boundaries and for smart marketing.
Sony has attempted to stake out the "middle ground" in the camera world: not as small as M43, not as large and professional as Canikon. High IQ, relatively small packaging, it's been fairly successful, but not earth-shattering.
What I see with this announcement is the ability to sell the Sony Alpha system to everyone. P&S users can move to NEX by purchasing a cheap NEX3 system knowing they can migrate to a world-class e-mount full frame camera in future. Sony Alpha DSLR users can purchase their professional line knowing they can easily adapt their lenses to a much smaller system as backup or for travel or other photography where size/weight matters. Add in the option for both APS-C and FF and it's even more compelling.
I do believe these cameras will become a cornerstone / reason for many people looking to decide on a camera system for the future.
Not just the iPhone, but many of the later generation smartphones are perfectly acceptable replacements for "point and click" compacts and for gimmick shots like panorama (linear in the case of iPhone, or spherical in the case of Android). That camera market segment is rapidly disappearing as a result, with phones used to capture moments when one doesn't have a quality camera along. The only thing that caught my eye with these particular pictures was the apparently high-quality in-camera panorama stitching. Good to see phone manufacturers competing on this basis- it brings nothing but goodness for us consumers.
Lots of great cameras on this list. For me, the photography made possible by the RX-1 differentiates it. Having a spectacular 24MP Full-Frame sensor (have you seen the high ISO samples!?!) and immaculate 35mm macro-capable Zeiss lens in a camera that slips into a pocket makes this the camera that everyone wants, even if we mostly can't afford it... and even there, the closest camera feature-wise would cost 2-3x as much and weigh 5x as much.
If I could have any camera on that list, I would chose the RX-1, so it gets my vote.
