Most of the complaints here seem to be from Plus model users. My complaints:
- Coming from an SE, it’s yuge. My upgrade from the 5S to the 6+ didn’t last a week, so migrated to the 6, which was tolerable, but still had a less comfortable footprint than the 5S. I still used it for a year, then moved on to the SE. I suspect that many 4x/5x/SE users will find the X too big, but for me it’s the upper limit of what I find comfortable, so it’s not a dealbreaker due to screen upgrade. The screen is gigantic next to the 4” models, which was intellectually obvious but still jarring when physically seeing them side by side.
- The stretch to reach Control Center. I hold the phone in my left hand, so having CC in the opposite corner relative to my thumb is in the absolute worst area for such a frequently used utility.
- I definitely prefer Face ID over Touch ID, since it effectively eliminates unlocking as an explicit gesture, but the range is limited, which is why I can't get it to work in my under-dash car mount for CarPlay (but can still use CP when the phone is locked), and why some people are having trouble getting the phone to unlock on their desk. Nilay Patel did a follow-up to his erratic results with Face ID unlocks, and was told by Apple that it’s optimized for up to 20”. Nilay has a habit, when walking outdoors, of looking at his phone from extended arm’s distance. Most users arch their arm when looking at their phone, so they won't run into that problem.
- I’d prefer the Home Indicator to only display when the screen is touched. Like a previous poster, I don’t like see the white bar in the Kindle app, though it doesn’t disgust me nearly enough to return the phone.
- Some physical elements I already knew to expect: rounded edges, the side-mounted wake button, and the camera bump. The SE has flat edges, a flush lens, and a top-mounted wake button. With the X, I'm always hitting the wake button accidentally every other time I grab the phone. Though I never use cases (I don't drop phones), I've ordered one this time for traction and to level out the camera bump.
