Honestly I think the idea of hundreds of tiny instances of Mastodon or Lemmy is not the way the fediverse should work. It probably won’t work that way because it doesn’t scale well. However, having a half-dozen or so large instances would give you almost the entire benefit without as many of the issues. Would Reddit be having a meltdown right now if there was even just one other instance of Reddit everyone could move to?
I think federation and centralization is the key to success.
In my family, everyone else has an iPhone and I have Samsung S23. So I can maybe give both perspectives. If you just want a phone to be a phone, it’s hard to go wrong with an iPhone. It’s always the best default choice. That being said, I personally can’t go back to an iPhone. Lots of people recommend Google devices because of the “stock” Android experience but I greatly prefer the interface, integration, and customization of Samsung devices.
Anyway, in no particular order why I like Android/Samsung:
I can probably think of more but that’s a good start.
