I'll assume this will be very biased cos of the forum this is but let's see haha. I'm on my second iPhone, after a 6 Plus. Nine months in on the 6S but frankly I'm bored. I was Android prior to my 6 Plus - which I bought in 2015 and now considering the 3T, but two things are holding me back; the cost and whether I'd actually miss iOS. I can buy the 3T outright, but then I'll have to finish paying off the 6S as well as having just paid out for the 3T. Or I can buy the 3T, sell the 6S on eBay, those funds would cover the cost of the 3T, then I'd just pay off the iPhone as normal. Second option being my better option but what does the iPhone 6S have that the 3T doesn't, and can justify me keeping it? Costs aside.
