The right side layout is very close to the RX1 but in most respects it is quite a bit better, I feel. Very nice detent resistance, the EC is stiff but will loosen up with use. The top plate could have been extended rearwards by 3-4mm to facilitate the EC dial, and the top rear dial could be recessed into that plate a little more to compensate. I have the top rear dial to do EC also, in fact.
The vertical shutter button insists on a vertical orientation to the index finger (a la Leica), which gives more room for the thumb to operate the af/mf / ael button and both rear dials. The shutter release, when half pressed, is nicely recessed into the surrounding on/off switch. You can lean the finger pad across it easily, and anchor the finger on the edge of the top plate, just in front of/above the EC dial.
The af/mf / ael button surround stands proud a little and is easy for the thumb to recognise when holding the camera to the eye. Finding it means the thumb 'finds' the rear dial located just above. All this works better than the RX1 which has easily confused flat small buttons.
Wisely the left hand is entirely free to hold the lens, set focus and aperture on (manual) lens.
But I am an A mode manual lens shooter who uses EC (post metering SS really) and ISO to fine-tune, so I just need a good focus assist button - that is the af/mf / ael one. For AF lenses, I would swap the switch on the af/mf / ael button to do Focus, have set one of the C buttons to focus assist and the top front dial to aperture setting - flip the switch, ready to go. I don't like using too many buttons or wheels.
August, use '1' or '2' for different global settings, they never ever change when reactivated. So set up your preferences in one go then 'memorise' them to setting 1 or 2. Sonys are 'learning by doing' cameras, no matter how many hundreds/thousands of pages Gary Friedman writes...
