Honest question: how would you even approach the Android? My smartphone is basically a more mobile extension of my laptop: sending document snapshots directly from the phone's camera to my MacOS desktop, starting iMessage conversations with anyone with a phone number on a Mac and continuing on my phone, copy-pasting from my laptop into my phone, etc.
Android seems to be designed to run in "I'm an island" mode, i.e. the phone is one and only computer a user is supposed to use. I understand that my usage pattern isn't what manufacturers (and Google) are optimizing for, but what would be the closest approximation?
