Feature-wise, my smartphone can be used for talking, and for texting, and for playing games, and for using the social networks, and for e-mail, and for internet browsing, and for just about anything that the iPhone can do.
Heck, my wife’s LG G2 was more advanced than the iPhone 6, and the G2 came out last year. The iPhone was just catching up to the technology that was already available in other phones from 2011-2014.
I don’t have the fingerprint reader in my phone, but then, I was never going to use it, and neither are the vast majority of people who do use smartphones. I’ll be using the CurrentC type tech that will be available to the general public some time in 2015.
So, basically, there isn’t anything in iPhones that people really do need to have that doesn’t exist in other phones.
So, you'll be using the CurrentC system that has ALREADY been hacked, stealing ID data from beta testers, the one that provides to the retailer the same kind of information that allows them to know everything about you, to have your credit information, to directly debit your bank account instantly by ACH transfer—which by international banking law you have only 48 hours to challenge any errors or fraudulent charges before they become irreversible and you have NO RECOURSE for recovery from your bank—and by which last year alone 375 million consumers in the USA had their data stolen from the retailers' POS servers of the very kind of data that CurrentC is going to provide, an insecure system that can be accessed by anyone who steals your phone? And you claim you're smart??? I don't think you know at all what you are talking about.
As for not using the fingerprint sensor? More of your confirmational bias. . . You can't use it, so no one will in your closed world. I use it multiple times every day. And I use ApplePay. Very convenient and easy.
