Linus, maybe you should watch Loius's video about the subject of Apple's recent changes.  He talks about how for them to get parts they require tons of information from the client and also can't stock any of these parts at their store but have to make the order with the customer's information.  So it'd be a 2 week turnaround to get their devices fixed still since after sending out for it and by the time it comes in and then it finally gets fixed.
