Jeff, I loved the RX100, and got many great shots with it. imho the best p&s out there, but I also got great results from the Canon S100. Decided to see if phone cam will do for p&s duties. Not sure it will work out, but got the best I could to give it a go. Looked at the Samsung S4 Zoom and decided it was a freak - no interest. Have had a Sony Xperia Z1 for a few weeks - 20 mp, 1/2.3" sensor and f/2.0 lens. Great specs, but still needs some work. One firmware update already, and cam definitely improved. Still a work in progress.
