THe home button has a quicker response time as stated previously, it's a press over a push. I'm not arguing the functionality, when in fact it's a convenience factor. Rather it be convenient or not to you, is your decision. It has far less travel than the previous button and it's quicker. Plenty of reads exist on the changes with the solid state button for reference.
And if you use a case on your iPhone 7, it also allows the Haptic feedback to be adjusted between 1-3, where the Haptic sensation can be experienced through the case and provide the user with a stronger feedback. Preference, soley depends on usage of the iPhone user.
@Channan quoted "
In fact, the solid state home button is less Functional than the previous home-button." Really? Were you aware the solid state button has a emergency function to tap on the screen if the solid state button fails To allow access? Does the previous generation home button have an emergency home button access if it fails and denying access for the user to gain entry to the home screen? If it doesn't, then your "Fact" isn't fact at all. From my understanding, if the push home Button fails on the previous iPhone , then the user receives an "Error 53" code read on the screen, rendering the iPhone bricked until serviced.
Gloves....please don't bring the gloves into this. Yes, I understand it's no longer a function. But please don't provide some altered dismay that the gloves feature is a make it or break it feature. It was an advantage in colder climates, but it doesn't and will not be considered a "Non-Buy" for iPhone users. Plus, there are several rant threads on this already and I certainly don't want to argue any more gloves complaints.
I know you mentioned a credit card difference in thickness. But, that's not how it's perceived through appearance and tactile aesthetic and feel. Naturally, the SE will
feel thicker based on the design. It's boxy, square like and edgey. Your claim may be accurate on the thickness, I'm not arguing that, but no one is thinking this way, because it doesn't appear this way because of the chassis design with the SE having an overhauled design in the hand and appearance. Where the iPhone 7 appears thinner, even if the differences are negated.
And even so, the iPhone 7 is thinner regardless, millimeter or not, my original point still exists. Rather it be noticeable, likely not. Which originates back to tactile feel. No one is pulling out a micrometer to assess the difference. It's the subconscious thinking when holding both iPhones, when one would easily assume the iPhone 7 feels thinner based on design. It really comes down to the Touch and feel.
Anecdotal Theory: Take both the iPhone 7 and iPhone SE/5s. Take five random individuals (Android or iPhone) and have them handle and feel both iPhones for certain tasks, I.e, texting, making calls and holding one handed or two handed for a duration. Then, take those five same individuals and ask them which iPhone feels thinner. I'm willing to wager 4/5 of those individuals would say the iPhone SE feels thicker based over the iPhone 7. Why? Because of the design and chasiss. Sure, the iPhone 7 may be more slippery or the SE may feel more boxy like, but.....T/L-D/R, is because it's based on feel, size and design.
Yes, once could pose the iPhone 7 is slippery with the contoured texture, which I have read many times customers stating it's has slipped out of their hand. All user based error unfortunately.
