I have the 10 and an iPhone SE. The iPhone SE obviously does not have 3D Touch and I often wish it did. It’s not a pain to not have it but definitely makes things more convenient, especially messaging on the lock screen. Once you start using it, you get used to it. If Apple’s goal is to make the phone thinner and/or lighter, I think they have done a good job with that already. Their goal must be to make the phone so light that it will blow away with a sudden breeze.
