i took mine back today. i was happier to leave with the iPhone 7 i'd traded in yesterday (amazingly, was still in the store) than i was with the X. really a bummer, as i was excited about the new tech, until i opened it. in fairness, i guess i didn't do enough homework, but...i was disappointed from the moment i opened the box. i've never had that experience with an apple product before, and hope i don't ever again.
that said, i didn't miss the home button at all, took just a few moments to get used to tapping the screen to wake it...but it just wasn't for me. i'm leery of face id, although it worked flawlessly. i thought the phone was heavy (i know, it's not really) and i didn't like the slightly sharp feel of the bezel to the screen. the notch didn't bother me. the camera bump on the back did.
also, if i'm being really honest, i like my white one...a silver back and black bezel just wasn't what i was looking for.
on the other hand, now that i have my 7 back, i'm back to loving my phone, and i saved over a thousand bucks. that's a good day.
