I’m tech agnostic; whatever fits my need is what I use, and I can easily change devices and operating systems without skipping a beat. My entire family and nearly all of my circle are in the Apple ecosystem; it just makes it easier to communicate and keep tabs on my parents. For those that aren’t using iMessage, Signal is the preferred app.
I still use Android for work, but the only thing I miss about Android is notifications. Apple can’t seem to get notifications right.
