Not sure if it matters to anyone else, but 4.2 now has group mms messaging, which is HUGE for me since all of my friends group message, and before the result was getting individual messages from each person, instead of a conversation among a number of people (like in ios).
That feature alone is worth having a nexus, and not having to wait forever for updates. As much as I want another non-nexus because of better hardware - ill never buy a non-nexus phone, and sadly - the nexus 4 isnt a big enough upgrade to get me to switch. I would kill for a nexus note. The demand is there - why not make a super premium phone and sell it for what the galaxy nexus sold for when it first came out.
Give me: 1080p, quad core, 5.5" screen, AOSP, great camera, etc, etc, etc.
