This transform ability has been a large part of why tablets became my primary computing platform. Android since Honeycomb, and iOS since iPadOS increasingly so, handle the whole mouse / monitor / keyboard thing pretty well.
Whether I’ve wanted a device docked that can be my work terminal, or to lean back on the couch, tablets have served me well. Aptly these are both environments where I’ll probably yell at you if you take away my keyboard, or force me to use a conventional laptop, lol.
Much of my advanced computer use revolves around an X-Terminal, so it’s been pretty easy to delegate other tasks like email and notes taking. Where as at home, I’m more likely to be focused on reading and messaging. Tasks that tend to benefit from either a keyboard centric use case with a big assed screen, or from a portable touch screen device.
