+1 re NFC, it is really nice to pair with the speakers with that. Then again, that is my only use case, and I know nobody that actually uses it for anything. My mates discovered NFC thanks to my speakers. In fact, the Nexus 5 is rubbish at it in comparison with older phones. Perhaps it isn't a popular feature, same case with MMS that affects a small fraction of people.

I still can't wait to play with the phone :-)
