Ya, SAMOLED is a HUGE bugaboo for me....especially since the news is the GS4 is still pentile
I'm not a jailbreaker or a rooter - prefer to simply set up and use, and don't mind the overlay so long as it isn't overpowering. If the battery life can be decent (just get me through a day on a day charge with pretty average usage) I think I'll be sold....
But I'm with you on the vanilla android opinion - if Google can wow with the Nexus 5 or Motorola Phone X, that will definitely be it. I don't have many complaints with the Nexus 4 - save the camera and the battery.

I stand corrected on the Pentile matrix of the GS4......from another thread:
This would take away one of my bigger disappointments with the GS4....while I'm still not a huge fan of AMOLED, the Pentile matrix really turned me completely off to the GS3
