I hear you. You want perfect. Just that nothing is perfect. It will be fixed, like iOS 10 was fixed.Well I couldnt be more satisfied with my iPad Pro 12.9. ProMotion display and all its hands down the best iDevice I own currently so I think the X will be excellent as well. I am always blown away by flagship Apple hardware on launch day. Its amazing how smooth and battery efficient Apple can make iOS if they set their mind to it. The iPhone 8 Plus is getting 14 hours of battery life. 14 hours. There is one screenshot showing a guy using his phone for 6 hours straight with 6 hours idle time and its still on 80%. My 7 Plus was like that on IOS 10. It no longer is. Apple devices are meant to be used on the iOS they ship with.
Just so you know, I report all animation glitches. Like you, I want them fixed.
