Re: One more thing -
Why did you feel the need to exactly specify which phone you were using?
Maybe a somewhat clumsy way to illustrate just how many docs he's lugging along in that phone? iPhones lack a decent file manager so you'd need an app unless you use the built-in reader thing, and it's actually quite a job to work out how much space something takes.
Alternatively it is to show off, of course, but that sort of p*ssing contest always ends up with discovering someone else who can throw more money at it. I'm willing to bet there are already a tonne of people drooling to get the iPhone X for no other reason that they can show off with it, not because it can do some amazing things (I'd be quite interested to see what else I could do with the facial recognition, but I have better use for such a lump of money, like getting an LG 43UD79 monitor :) ).
