I was coming from an iPhone 6 Plus originally that just so happened to have screen damage the month I paid it off (typical) so instead of getting it repaired, I reverted back to my iPhone 5 (regular) and said I'd wait for the next release. Since the X was announced alongside the 8/8 Plus, I opted to wait even longer for the X and I'm glad I did. The look of the phone is top notch and the quality is definitely solid. Keep in mind I'm coming from something much older where the quality standards, while high at the time, pail in comparison to today's iPhone.
I've had the iPhone X for six days now and don't even remember what using that Home button (that I've been using since the iPhone 3GS) is like. You'll forget it soon enough, too. The gestures are still very natural. I always hated how large the Plus model felt in my hands as doing anything "one-handed" was impossible, even using reachability. I feel that the X is a great balance between the non-Plus models and the Plus models and I did turn on reachability (it is turned off by default) to help reach some of the upper portions of the screen as I like using the phone one-handed.
Next to my wife's iPhone 7 Plus, the screen size is virtually the same between the two, while the X's form factor is overall smaller, which is real nice. The "notch" along the top edge of the screen isn't an issue for me, as it seems to be for some. Within time, third-party apps will adopt the new resolution and everything will be seamless when switching applications. I have no qualms about the display's brightness either, as I find myself setting it to the lowest setting quite frequently. It's very bright! The only con I would give for the screen is that the refresh rate is lower than I expected, as I sometimes catch the screen flicker slightly with the naked eye as the oLED refreshes.
I've never had Touch ID, so I cannot legitimately compare it to Face ID, but I can say that Face ID is very quick and intuitive. It was easy to setup and can be reset easily if desired. With Face ID, if there are notifications present and someone picks up your phone, they can only see what app is pushing the notification. The instance they hand the phone to you and you look at it, the specific notifications populate fully, which is nice if you're getting a text message that is for your eyes only. The only con (if you would call it that) I would give for Face ID is if your phone is sitting on a flat surface (such as a desk) and you're sitting next to it, your face is not within range of the sensor, so you have to either move into view/lift the phone into view, or enter the backup passcode to unlock the device.
The speed is blazingly fast compared to my previous phones by far, while the battery life smashes any other iPhone I've had. I haven't charged it wirelessly so can't comment on that. I'll likely wait until Apple releases their own charging pad so I can use it with my Apple Watch. The sound output kinda blew me away too, as I've been finding myself turning it down, when I'm used to turning it up in the past. I don't care that they dropped the audio jack, as it's a wireless world we live in today. Thankfully for those of you who do require the audio jack, they include a Lightning to 3.5mm dongle adapter. As far as the camera, I was able to take amazing photos at a car show over the weekend, and the 4K video is stunningly crisp and smooth with it's dual stabilizing camera sensors. I'm in love with my phone again, and it's been awhile.
The price I feel is fair in today's market. Yes, I paid $150 extra for the 256GB, but feel it's still very much worth the up-charge when the base only comes with 64GB. Photos, songs and videos add up quick, not to mention apps. The payment plan with your carrier makes it a little easier to swallow, and isn't much more than what my iPhone 6 Plus cost monthly back when it was new.
I recommend Apple Care Protection, which can be purchased separately up to 60 days after original purchase date. Get a phone cover and screen protector on-the-double! Best Buy has many options available and I bought both a moderate, slimline cover and a durable, more bulky cover, as well as a glass screen protector. You'll want to protect this investment for sure.
In short, if you've been holding out for three (or more) years like me, then this is definitely the iPhone you want to get. You will not be disappointed!
