Also, imo the platform walled gardens considerably hamper your ability to move away from a given vendor just because they made the current model less repairable. Plus, as other vendors see Apple's snowballing profit, they also adopt similar construction and thus you are left with pretty much no choice when you go out to buy a product. The only counterpoint I have in this regard is Microsoft Surface: their earlier models were terribly unrepairable but the newer ones seem to have considerably improved in this regard.
