I currently have a Samsung Epic 4g which I got 2 years ago (Apr 2011) and have had it replaced (through Best Buy's "Black Tie" program) 3 times. Through a mishap on Best Buy's part they gave me a free Galaxy Nexus. I really want to switch over to the Nexus but I keep hearing mixed reviews saying it's not that great and the battery sucks. I use my phone quite a bit especially for work (constantly needing to make phone calls). Should I switch over to the Nexus for now, and then upgrade to the Galaxy S III in April when my actual upgrade comes up????
