no offence but that is a really sweeping statement, and as an apple fan I feel it isn't accurate.
I use the 6+ 16gb, and yes, I don't take photos, don't load music and don't shoot videos, I stream movies but don't store, and for that I usually use my iPad.
the 16gb is more then sufficient now, but one reason I use this phone is because of it's stability.
the idea of transferring contacts and other info to my next phone conveniently through iCloud simply gets me addicted.
the phone looks good, is simple to use and has a wide variety of casings for you to change the look and feel of the physical phone every once in a while.
lastly, my 6+ cost me a grand total of $59 bucks.
so why not 16gb?
