I am not condemning Apple product right now, but the way Apple running their business and marketing has making me a little bit uncomfortable. I still love their design though, can’t deny Apple has been a design trend creator and a lot others are just follower 
Apple hardware and Apple software
Apple product come with such a premium price for a reason. They owe everything including you as well. As long as you buy something from Apple, you will going to get the rest of the product from them, beside of course, the accessories.
One place to get replace
Only authorized Apple reseller has the right and legal document to replace your faulty machine, or just a simple warranty from Apple care. Obviously this limited to big city around the World and not small town in a country. Isn’t it exclusive and expensive? Unlike changing projector headlights where you can get it on most store in town.
You are their asset
As soon as you jumped into Apple product, you are their asset. Because you have only one way to go, what do you think they are you to “switch” instead of “getting used”? By taking it one way only, you will become their royalty customer.
Now if you asking me will Linux works this way? I would probably say yes. For me, basically Linux and Apple are both very alike, the only thing lack in Linux was the publicity, which Ubuntu has been working very hard on I believe. That will be another story
