I have 1 daily driver (personal) and 1 work.

The other is an old one that runs twitch / Spotify/ youtube while I work on a separate pair of headphones so the work productivity monitoring software doesn't pick it up.

I'm hybrid so I have to take the work computer into the office once a week and on work travel trips

My daily driver also has to be portable so I can play games next to my wife on the sofa sometimes, or I also use it for video, voice over and music editing so being able to move it also helps.

Also I sometimes use the twitch/spotify/youtube laptop to show sheet music while I record on my daily driver without worrying about fan noise.
