I was just in the local T-Mobile corporate store today and was asking the sales folks what the hottest devices are at the moment and without hesitation they said the iPhone X and the Note 8 and they have a hard time keeping them in stock. So even though I have heard they are cutting back on production, I think the X is going to be around for a while.
I also spent time asking the two sales folks about how they liked their iPhone X and they love the device and said after a short adjustment getting use to the gesture concept, they have forgot about the home button and would find it hard to go back to using one, thats some positive feedback.
By the way, I also helped out on a sale of an X to a couple who where on the fence between the X and a 8 plus, after I did a demo and let them play with my device, they both bought the X, mission successful.
