Two "pros" I would add to the list are NFC and Induction charging.
While I look forward to experimenting with the former, I'm enjoying Induction charging much more than I thought I would...
...although I had to "level" the Energizer charger to keep the slick backed Nexus4 from crawling off the smooth slanted charging surface.
Another plus is the apparent improvement in voice recognition and/or microphone... the recognition is far better than on the Nexus7 and reliable enough to use for almost all text input needs.
