If you don’t own it, it owns you.
Also, as much as I love TESLA, less control and ownership. You are still tied to the TESLA supercharger network (centralized). Also the over the air updates — you cannot hack or modify it. If you cannot modify, edit, fix, or service your own car or things — you don’t have full ownership.
Also, in terms of owning the service and power of the tool — laptop is superior to phone. Phone, iPad (iOS) you are still tied to the Apple platform. At least with MacBook laptops you have 1000x more freedom.
