After the hype (and disappointment) of the Nexus 4's launch, I'm thinking I should try Android out to see if it's a OS I really want to use. I'm thinking about taking advantage of the carriers' 14-day return policies to buy a phone, try it out and return it. That'll give me 2 weeks to decide whether I like it or not, and I'll be 2 weeks closer to the Nexus 4 being restocked if I decide I do want to switch. Any recommendations? The Samsung GS3?
