I've largely ignored NFC, but after reading a thread in the Nexus 4 subforum, I have ordered some smart tags on Amazon. Can't wait to play with them when they arrive.
The new iPhone looks like the same thing they've been pumping out for years.
The 64 bit processor is a gimmick. With less than 4 GB of RAM and the time it will take for developers to catch on, there is no added benefit. Sure it will be faster, due to a better architecture, but it's not because it's a 64 bit processor.
