My last iPhone purchase was a 6s+, last subsidized available phone from AT&T. X looks cool, but I know to not buy a phone with new tech like Face ID on the first version, they will make it much faster and more reliable next year, there is already a rumor that the 30,000 dot camera that projects the dots on your face was the bottleneck and to fix the bottleneck Apple has started to allow components to be installed that do not project the 30,000 dots, as they were not making it past QC at 30,000 dots threshold. Apple denies this but I don’t believe them.
I still own all Apple stuff. I fully believe what you buy and how much you spend Apple gives you a score, and for events every account has it’s score attached and they allow the people who spend the most money to get through on launch windows.
