Agreed, the iPhone is a bit of an elephant in the room here. Particularly when the author waxes lyrical about how nice it is to have front and back made of Gorilla Glass (exactly like the recently-superseded iPhone 4/4S).
Apples to oranges. iPhone 5 is severely limited when purchased in the US: you can't unlock and put a different (overseas) carrier's SIM when you're out of country, until you complete your 2 year contract.
Unsubsidized, the iPhone is $699. Unsubsidized Nexus 4 is $350.
