I've had my iPhone X just over a week and I adore her! She's brought fun back into using an iPhone after using a series of iPhones which all seemed pretty much alike in their form factor and functionality.
Coming from a jet black 7 Plus, I love the smaller size, which is far more comfortable to hold, especially during lengthy phone conversations. The swiping and gestures are intuitive and it took me very little time to get used to them -- I really don't miss the home button at all. (Only problem is that now I find myself trying to swipe up on my iPads!) I had been a bit hesitant about Face ID but it has worked flawlessly for me so far, no problems with glasses or without (when I set it up I didn't have glasses on) and I don't usually wear hats but don't anticipate issues there either. I prop the iPhone on a stand on my computer workstation and when a new message comes in, I look at the phone, Face ID does its magic and voila! I also am appreciating being able to tuck the iPhone into a pocket now, which is something I hadn't done with the various Plus phones I had. The screen -- oh, that gorgeous screen!!!! Colors just pop! At home I keep the phone naked, but when going out I slip her into either the Apple folio case or the Apple silicone Product Red case. Now that they've announced a new Spicy Orange case, I'll be grabbing one of those, too, since orange is my favorite color.
Battery life is amazing -- my iPhone 7 Plus was starting to lose charge more quickly, so I'm enjoying having great battery life again. I'm delighted with how fast this thing is, too -- what's not to love about that?!
