Facebook – don’t use it, and very unlikely to start.
Apple – most people choose to either go Apple or M$. I went M$.
Amazon – great product selection, but their shipping is becoming less and less practical for me. About the only thing I’d miss is my cat food subscribe and save. Kindle would also be annoying to port to another platform.
M$ and Alphabet tie for hardest to abandon. All my digital stuff is tied up in PCs, and I use Google quite frequently at work.
