I'm new to Sony (I've been an HTC man for years) but loving my Z1. I'd say no to the Qi wireless charging. I've got the dock and was a bit disappointed to be honest - no charging via the usb cable it came with, has to be plugged in to the mains. My charger fitting case (not much choice) didn't fit so I had to cut out a couple of bits on the adapter.
It is easy to use but you have to have the phone connected (by magnets) into the exact right position to connect & charge.
Overall I'd say over priced but better than always using the USB lead - I'm scared I break off the cover.
