iPhone + apple watch + AirPods
iPad pro + apple pencil + apple tv (love it as a teacher in the classroom)
Yes, these innovations may not sound as sexy as being able to turn your phone into a desktop, but they are meaningful innovations which I am using every day to great effect, and it all adds up. Every day in the classroom, my iPad is mirrored to my apple tv and I annotate on my documents with the apple pencil, which offers a sublime writing experience. The best headphones are the ones I have on me, and I love that my AirPods are so convenient and portable. My apple watch is my remote for podcasts and music, plus I use apple pay on it extensively, not to mention notifications and the odd app here and there.
Apple has complete control over their hardware, software and services and it shows in how they are able to make their products all work together in a manner that no other competitor can replicate.
