Pros: a. With the exception of their keyboards and pointing devices, Apple hardware products are well designed, well built and rugged. They tend to cost more but this is counterbalanced since their service life is longer.
b. Apple software also tends to be easy and intuitive to learn, stable and non-problematic. Not bewilderingly overdesigned and overloaded with a plethora of "features" like the software put out by such companies as Office, the CSS suite, and Quicken. Apple is a great industrial design shop that fully understands the value of simplicity.
c. The "ecology" (i. e. the way various Apple products interact with each other) is stable, reliable and easy to use.
d. I approve of Apple's strong commitment to maintaining security and protecting the privacy rights of individual users. Am expected to trust one enterprise (Android) of a corporation which has a poor track record in this area regarding others of its enterprises (Google)?
Cons: a.) the corporate culture is very paternalistic in the sense its users are given what the company thinks they ought to have rather than asking them what they want (market research is not exactly Apple's long suit).
b.) This a proclivity for one-size-fits-all solutions especially when combined with the "walled garden" approach. For ex., not equipping its AirPods with a selection of replaceable ear tips to accommodate different sizes and shape of ears. And we can only use our HomePods for a limited range of Apple-approved purposes (you can't use them in the home theater or sound system of you choice). A HomePod equipped with Bluetooth circuitry would be a far, far more flexible and useful item and justifiable purchase. If it wanted to, Apple could market a dongle that would make every device equipped with an audio out jack AirPlay-friendly.
c. The general lousiness of iTunes, which has gradually morphed from a tool that helps the user ride herd over his media into a portal for Apple Music.
d. An occasional tendency to allege security protection as a means of justifying policies that sometimes come at least dangerously close to monopolistic business practices.
