Had a GNex for 3 days, Missed the Spectrum - Came back 
Getting your data onto GNex was not swapping a card - but having both phones attached to laptop and then copying files over
Device came installed with AOKP Milestone 6 - wonderful ROM. All you can dream of and more
but that is where the dream ends and the nightmare begins.
I did not know but I work in "low signal" areas - On the Spectrum - sometimes I'd hit 3G but mostly 4G. So the laptop goes nice and fast and with a tail wind I can even catch a movie (not really - who has time for that).
On the GNex - however there was no 4G (and it was not the ROM or the Radio)
I tried another ROM and another Radio - No 4G, however once out of the area - it caught 4G just fine.
One other thing - when a call came in - it dropped the internet for me, a big no no no. So we booted up the Spectrum - yes I'm running stock V6 it does all what is needed. Bye Bye GNex - currently sitting on Ebay.
