OK, I have to say, I know I spent a lot of money and I'm only going up from the 6S Plus, but it does seem snappier.
And no, I'm not being funny, IE: Jimmie Kimmel.
It really does seem crisper and snappier. I'm sure it's just the newness of the thing, but so far I'm really digging it. Even the home button is ok. Funny thing is, the old home button in iOS 10 really sucks. I couldn't get Apple Pay to work, and it never would act the way I wanted it to act, even after I changed the settings back, but the new iPhone 7 "buttonless" functions flawlessly. It's quite obvious that iOS 10 was designed around the iPhone 7. Someone's asking for a user review. I'll try and type one up and get it out to him. So far, while it's not worth what I paid, it is an improvement over my 6S Plus, IMO.
