The repair experience for MacBooks (not iOS!) is abysmal, even at Apple Stores. Whereas other vendors (HP, Dell, Lenovo) will happily send you customer-replaceable parts (keyboards, disks, etc.) or a technician for on-site NBD repairs even with their standard warranty plans, Apple requires you to buy Apple Care (~10% premium) and then you still have to wait for appointments and repairs at the Genius Bar. This can easily take a week or two, and they do not provide a loaner devices so you’re without your computer for the duration of the repair. I’ve been told that there are professional Apple Care plans that do provide them, but they come at a (even higher) price.
