I'm on episode 4 night... I'll PM you to discuss so as not to put any spoilers out there for the other girls lol.
Really hard to say... If it were myself, I would have to think about what size iphone I have. If you have the largest one, then I would say yes, but if you have a smaller sized phone, then I would say no, however I would think about if I were going to upgrade my phone soon or not and if so, what size would I get. And if you don't plan on switching phones any time soon to a plus, I would say it's not redundant. My two cents =) I have been debating whether to get a new ipad mini for over a year now lol. I have several much older apple products, including ipad, itouch, nano, mini, and would like to consolidate into only a few items but each newer version of the device does different things that I want, or lacks. My only option is really an iphone, but I don't want to give up my blackberry... it's been a debate I've been having for a very long time and that's why I haven't bought anything lol
