Not crazy at all, the 8 is a great phone and will be for another few years still. I'm sure there are great deals to be found too.
This. Best Buy, Fry's, Walmart, Target seem to have semi-regular sales on it. Carrier deals. Add in price will soon drop, can pick up a really nice phone for a nice price.
Like OP, I carry the phone in my front pocket, so the 8 is a great size for that, fits into coat and suit coat pockets. For me, sits comfortably in my hand. Fast processor and the new A12 processor is not that much faster from what I recall from the presentation (seem to recall that the two big cores have a 15% speed improvement, but all the cores have better power usage performance). Imo, phone processors, for most people, are overly sufficient for their needs, so, no need to go chasing processor upgrades: most people will not tax it and the 8 should have sufficient runway.
Will be interesting for me in 2020. I have normally updated my phones every three years, so, can sit it out to see what happens to the iPhone line, if they bring back some smaller device. If not, by then would have got hands-on with Xr, can see how the 8 handles iOS 14, battery health on the 8: might be able to stretch things out one extra year and then pull the trigger on the 2021 X (X is not much bigger than the 8, and could live with that, just hate the price; Xr is too close to being Plus in size, so, assume will not like as I do not like the Plus size phones in my hands).
