This High Sierra bug is bizarre and disturbing. But Apple would have to commit an act of outright betrayal (such as lying about FaceID off-device storage) before I would consider going back to Android. Not because I think there is concerted malice by the Android overseers (partly because that kind of control doesn't really exist as it does with Apple), but because the potential for negligent design to cause damage seems so much greater. And from the perspective of a long-time iOS user, it seems that Samsung has a potentially strong hold on the Android ecosystem. And I trust their security and design chops far less than I do Apple's.

That said, I could see myself sharing your same disillusionment if I have to upgrade from my 4.5 year old Macbook Pro. I don't think I've ever had a laptop for more than 3 years, and I was happy to have an even shorter cycle when it came to Apple computers. I helped a good friend purchase a new MBP, and the most I can say is that I'm happier that she's on the MBP than on the old Dell laptop that she reverted from Windows 7/10 to XP. But I'm willing to wait another year or 2 for a improved model.
