For me "sucks" describes something bad, tasteless, something done sloppy, something that shouldn't have happened. Judging from your comments, it's not that it flat out doesn't work for you, just that you wish it worked from more angles and faster.
So with that in mind, I have to ask - is "sucks" really the first thing that comes to your mind when talking about a system that recognizes your face, even in pitch darkness? I mean, there are aspects of it that are not perfect sure, but at the same time it's some really advanced tech, it's futuristic, it's something I only dreamed of as a kid. It's one step closer to Star Trek, and sure, there are certain improvements that will make it even better, but I am always surprised by the amount of negativity and cynicism about new technologies from people, especially on a forum like this. Once, computers used to excite people, now it's "my phone doesn't recognize me from EVERY angle". You're entitled to your opinion, but I'm certanly glad I'm still able to enjoy cutting edge technology. Yes, even if it takes 0.8s longer to unlock (although I think it's faster in practice, but that's besides the point).
Here's an example to illustrate what I mean: imagine you could unlock your phone with your MIND. Someone comes up with the technology that somehow reads your brain waves and you have to think of the word "unlock" and the lock screen will go away. But it takes a second longer than the classical method of unlock and sometimes it happens that it misinterprets your thoughts and you have to try again. But it's ****ing MIND UNLOCK! I would be incredibly excited to try and use this tech. But critics from Macrumors? They would want their Touch ID back.
Talk about glass half empty.
Broooo...... you’re taking this waaaaaay too seriously. Trust me, I’m thankful to have a phone, let alone an iPhone X. I myself know these are first world problems... I’m not sitting at home fuming over it. It was just a post. Would I like to have Touch ID back? Sure. Do I miss it, yes. Am I going to write a 3 paragraph post about it..... nope.... lol. It’s not that deep to me.... Bro. Get out. Get some fresh air..... it’s beautiful outside. Don’t take these posts so seriously and personal.....
