JURY'S STILL OUT ON:
I've had this phone for a little more than 24 hours now, and my initial thoughts are "wow". This phone is amazing! It's a beautiful phone to look at, what about the new features? How's not having a home button, for instance? Truth is, I'm starting to like it even more.
Swiping feels more natural on this phone than clicking a button, and pulling out your phone to check a notification, and it automatically recognizes you and unlocks is really nice. I'd say it's quicker than having a fingerprint reader, but is it more secure? Apple says it is (1-50,000 chance of some random person getting into your phone with bio-metric scanner, to 1-1,000,000 with FaceID), but time will tell. It works as advertised. It even works in the dark. It does have difficulty on a flat surface, but for me, it's not a big deal. The display is AMAZING. Perfect blacks, without color over-saturation. It is very pleasing to look at.
What about the battery life? It's hard to say. I have been able to get through an entire day's use with it, but since I have only had it for 24 hours, I can't tell you about long term. Apple says 21 hours of talk time, and 13 hours of internet time, and so far, I've had no reason to doubt that.
Which goes into my next topic: durability. Will it last for a long time? At $1,000 it better be good quality, and being an Apple product, that's a safe assumption. The phone looks very well-built. Premium components went into this phone, and you can tell. It's water-resistant up to 3 feet, dust, scratch, and fingerprint resistant, as well. I've not tested it in water (and have no plans to), but from the surface, this phone is very solidly built. I'd still recommend getting a good case and screen protector, though (as I would with any new phone).
Is it worth the extra money? Yes and no. It's a unique, but also a better experience than past iPhones, but if you really like Apple's style they've had since iPhone 6, and dead-set on keeping that style, you might not like the new one. Much of the hardware is similar in the X as it is in the 8+.
The main selling points and differences on this phone is the OLED display, which, in my opinion, is the best on any phone, EVER, the rear dual-lens camera with optical image stabilization on both lenses (only one OIS on one lens on the 8+), and FaceID. If you don't need the extra goodies, then you'll be happy with the iPhone 8+, or at the minimum, the iPhone 8.
But, if you're willing to drop the money for this phone, and you're ready for a new experience, I'd say you won't be disappointed. Great phone!
