Outside of Microsoft (disclosure: MS employee), I don't see much competition for Apple in the innovative premium tablet space. They still execute well in the phone space, watch seems to be shaping up fine, they are still the only PC maker that is known for producing PCs that can last. The costs don't seem too off from the competition, unless we are talking about Xiaomi or Lenovo, but then the tradeoffs are obvious (no longer in the premium space).
I do see Apple slowing down a bit in innovation. I mean, if iPad Pro was released last year (stylus, yeh!), I might have bought it, but the Surface 3 came out instead, which is quite decent (I won't go SP3 because of the fan). But Apple is still executing well, they aren't making many mistakes. They have built up a loyal fanbase and haven't done anything to betray them yet.
People who depend on tech are usually about the shiny more than normal consumers, who just want to get what they need done. The rabid irrational Apple fanboy isn't grandma, no, it is the young kid working in tech.
