This is good until thanksgiving/year end sale comes.
iphone 8 is not so attractive, but iphone X is ! it is priced higher as many of the iphone 6 users will go for it. Iphone 6 & plus was major success, in apple history, and it is getting older now. Most of the users are likely to recycle to new version, that is iphone X. Priced higher will increase the revenue and profit margin.
You will hear record sales of iphone 8 - this quarter and iphone X - next quarter. Normally, well established companies like AAPL meet the target sales/revenue (rarely miss).
In iphone X, apple matched all Samsung standards, retina, OLED, camera, wireless charging, size etc.
Iphone X, in my guess work, will sell better than expected. Oct-Dec sales of Apple is very high and net income around 18B for that QTR. This will reflect before Mar 2018. All these, including Buffet ownership, brings the AAPL to peak market cap 1 Trillion well before Mar 2018.
Amazon or Google or Facebook can not match Apple at this stage.
