I am torn between an Optimus and an Epic (posted a which-phone-should-I-get question in the general forum if you want to weigh in). My question is - what do you like best about your Epic? What makes it, in your opinion, worth the extra up-front and monthly cost? I'm hoping to find things that I would value (or conversely, that wouldn't matter to me) to help guide my decision. Thanks in advance!
