Apple isn't great at building low-value-add products. They shy away from these. TVs are a prime example where they can't add value beyond an AppleTV set top box.
- The set top box works with any TV and it's one SKU. The number of sizes/screen quality/prices that people would require from a TV is so not apple's MO. As much as apple loves integration, they'd prefer a one-SKU device more.
- Airplay is value, but they haven't really added to it lately. The existing AppleTV already does it, and so do 3rd party tvs.
- TVs are very low margin, and they don't own screen manufacturing so they're likely not able to take outsized profits from the market.
Regarding the Car
- Its an open question if they're still doing it, but maybe like the TV, they shouldn't wont...
- They want to control the software and GUI and that's done now. Unless they want to control the car itself (eg. doors, alarms, etc. or self-driving) they don't need deeper integration.
- Cars are very complex, even for apple standards - and not complex in the way apple is familiar with. They have no experience building or differentiating in this industry (like screens wrt to TVs but 1000x less experience).
- CarPlay added tremendous value, and most cars have it now. Deeper integration of the phone as the brains makes sense. But does anything else?
