I broke down and got the Galaxy S3 and couldn't be happier. I went out to Costco on Black Friday, got a 16 GB in white for $50 (after a rebate) and was able to use my brothers upgrade (whos on a flip phone plan) to keep my unlimited data. After contemplating the Nexus 4, the cons outweighed the pros and the Galaxy S3 seemed like a no brainer- it has a huge dev base, is a widely popular phone and should be supported for a while. The biggest flaw with the Nexus is the stupid lack of storage, which is mind-numbingly low- why does Google want to suddenly cripple its users ability to store photos, music and stuff on their phones is beyond me.
Looking back, I wish I did this earlier, but I have no complaints on the discount I got on BF. If your looking right now, I think the GS3 is the way to go. Not a big HTC fan after my Thunderbolt experience and I need an unlocked bootloader since I want to easily flash ROMs on my phone (making the Razr Maxx HD out). And the Note II is too huge. My contract will be done in May, and if VZ ever takes away my unlimited data, I'll consider jumping ship then. For now, I'll enjoy my unlimited data, my excess storage capacity, and sweet new phone.
