I got the X today and have had every single model before this, including the 8.
I'd agree with what a few of the others are saying....the screen is nice, but it doesn't blow anything away. If you're comparing it to a Galaxy device, you may be disappointed. Matching it up against my 8 didn't show much difference, other than size. I'd stress, it's not bad at all, it's very nice....just keep your expectations in check.
I also saw the yellowish tint this morning when I picked it up. It was literally the first thing that caught my eye about the device after the form factor. As the day has gone on, I think I've gotten use to it, though. No doubt in my mind it can probably be optimized with a software update, too. I've been keeping the true-tone on.
