IMO, the iphone 4s camera took better pictures that my z1 Compact, but its not a massive difference, and with some fiddling of the manual settings you can get good pics.
The magnetic charging socket works far better with docks than with a USB cable. I bought a couple of these...

Battery life and speed are great on the Z1 though. Also like the USB host cable for connecting a HDD (or Garmin Edge for uploading whilst on holiday).
[quote=niloC ]For those with the Sony Z1, Z1C or Z2 what's the quality of the photos?
I don't know what you're expecting from a phone but here's one I took the other night in quite challenging light conditions
