It seems like a lot of people on here are saying that 1GB is all we "needed" right now. Like Apple made this executive decision with end-user experience strictly under consideration when it was more likely financial in nature. Is the iPhone 6 and 6+ usable? Of course. Is it the best phone out there in our opinions? Of course, that's why we bought one. Even the best things out there have flaws, however.
I don't think someone here, the choice given, would vote for 1 Gb.
That's quite different from saying that the iPhone 6+ with 1 Gb is good only for sms and phone call like someone is absurdly writing.
