I'm trying out a Samsung Galaxy S7 tablet with a keyboard case and the S-pen. It's really close to the phone from a operating system perspective. The positive is that all the phone Android apps work on it. I mostly use free and open source apps, but some propriatary I have to use like the one for connecting to my Sony A7C camera. The bad thing is that it's not really a desktop OS, that means that none of the keyboard shortcuts which I use constantly work and I always need to touch the screen to do the simplest things.
