The only part of Apple's ecosystem that has ever held a central place in my life are macs. Since 2013 I've used Macbook Pros as my primary development machine and arbitrary android devices for my phone. I did also buy an iPad 3 which I still have, but it's never been very useful beyond being a browsing or reading device. I don't really buy any claims of being locked in, I use macs because they're preferable, and tend to keep them for a long time. Windows is a trashheap, don't feel like bothering with Linux.

I haven't upgraded my intel macbook pro from 2019 just because the ram and ssd upgrade are irritatingly expensive, but eventually I'm sure it'll be tolerable somehow, either because my current one has become wildly too slow or because the cost comes down.

I have no reason to buy an iPhone, so I don't, what's the problem?
