I’m satisfied with Android, but I acknowledge the potential of the Apple ecosystem. It’s true that once you’re in their world, it becomes hard to consider other options, as Apple users tell me. However, today we have a wide range of choices in the market.

Regarding Buffett’s decision to sell Apple, he later explained that his choices were influenced by tax considerations. The significant profits generated by Apple could impact these decisions, especially in the context of a growing fiscal deficit in the United States, which might lead to higher taxes in the future.

I'm not thinking about using a branded cellphone, because now there are so many cellphone brands, I'll just use Samsung or try swapping it for an iPhone 15.

I highly doubt it. Apple is quite conservative with the changes that they make to the iPhone every year but they’re not going anywhere. Apple has their entire walled garden ecosystem to keep people from leaving: iPhone, Apple Watch, iMessage, ApplePay, AppleCard, FaceTime, Family Sharing, etc all create a synergistic ecosystem that helps retain users.
