You are missing the point.
If you wanted a phone the size of the S7, you now only have a choice for something akin to the S7e and other 5.5" phablets, which for a lot of people was that bit too big.
I downsized all my phones last year and feel better for it, yet Samsung have now abandoned me, (doubly abandoned if you preferred a flat screen too) and are forcing phablets dimensions on us if we wanted to get an S8, regardless of how much extra screen they have crammed into the body.
For many folks, this will be a problem if they prefer 5" devices dimension wise .
I've recently downsized too, going from 7 Plus and Note 5 to regular 7 and flat S7 and am generally happy too, doesn't feel like a choir carrying around my handsets anymore and I feel the iPhone 7 might be the perfect physical size. While I do at times miss the larger screen, I feel I'm over just having a larger display unless there's additional functionality associated with it (such as the spen).
Looking forward to the Note 8 and iPhone 8 later this year.
