This is unequivocally untrue relative to a dedicated reading device. Until iPads have e-ink technology (or something that is completely non-reflective), reading a book on an iPad/tablet vs a dedicated reading device (Kindle, nook, etc.) is as different as driving a car and flying an airplane.
For heavy readers there is a tangible difference. But for light readers, MANY can get by with using a tablet as a reader. The market is shrinking for exclusive readers because of this.
There are still Buggy Whip manufactures in existence, it's just that the market is tiny compared to the late 1800s.

Are you saying it might have to connect to a network to unlock your phone via fingerprint? That would be ridiculous for many different reasons, principally being that storage space required for fingerprint recognition is so much less than that need for Siri. Why do that? (unless you believe the tinfoil hat wearing conspiracy theorists who would have you believe Apple is including this feature to give up our privacy info to the NSA).
Yeah, because tech companies have kept all user info under strict lock and key from the NSA
