You're on the ropes Apple. You NEED to start listening to your customers.
You already lost Pro users that kept you alive during the pre-iPhone years.
Your sales says that smartphone users are going elsewhere and I don't blame them. Going elsewhere gets you:
Fully functional virtual assistant.
Fully functional and accurate Maps directions.
Fully functional cloud based Photos app that just works, with automatic face recognition, albums, and geotagging.
Fully functional music service that blends with your personal files without a bunch of work arounds or hoopla.
Default apps
Easier to use inter-app operability.
Delete of unwanted apps, especially apps that haven't had new features since 1.0
I could go on, but you get the point.
I'm exciting for Homekit, but I'm also not because I know that Apple will barely update the app and will wait 1 whole year to add new features, if any, as an iOS udpate instead of add features as they become available.
