For me this is where Apple's walled garden shines - my work laptop is a MacBook and I own an iPad for personal use. The iPad can connect to the laptop and function as a (high quality albeit small) secondary display. And then I have an entertainment device the rest of the time instead of just a monitor taking up bag space.
They're very affordable now too. I got one for something like $80 and it's been great. Working remote and getting to visit friends and family during the week and still have more screen real estate is huge.
