EDIT: Apparently the conjecture below is totally wrong, as “iPhone 8 and 8 Plus are hits as Apple sells 46.7 million smartphones in Q4.”
Allegedly: “U.S. buyers favor iPhone 7 over 8: research.” We’ll see whether it’s true when the actual numbers come in, but I’ve been on the new-iPhone-every-two-years treadmill for a while, and when I looked at the new iPhones… I passed. The good one with 256GB of hard drive space ends up around $1,200 after tax. The iPhone 8 itself looks like a marginal improvement and still costs something like $800 or $900.
There are some improvements, but the big ones (like the double camera lens) are on the iPhone X. The iPhone 6s I have is good enough and has the key advantage of a headphone port. I replaced the battery for $60 and will punt for another year. Perhaps next year the OLED and dual-camera models will be standard and cheaper. For now, this looks like a great year to wait. Or buy a used iPhone 6s or 7.
