So I have the Galaxy S4 Mini... Kind of been itching to upgrade. Leaning toward this phone. I would purchase it outright. I found one bran new locally that somebody will sell for $500... 32Gig... I use my phone for calls, texting, a few pics here\there, surf the web here\there, Google Maps... You think it's worth $500 to go from the Galaxy s4 Mini to the S6 Edge?
