I put a couple use cases above on another comment, but as I'm reading through these another one popped into my head. I have a steamdeck with controllers as my media center, the other day I was playing a game and wanted to look something up on the wiki for it. I got it done on my phone but it was a ton of pinch zoom, search page and it was just tedious. So add that to the use cases.

As for macos, I am not in the apple ecosystem at all, I use a macbook air for my day job and it's serviceable but I'm just a linux guy really. If I can get KDE on it, then even better. I've been using KDE since slackware in the late 90's.

The macbook air is handy though, when I have to go to the office (occasional) I don't have to charge it and it's small enough to carry everywhere.

Being honest here, I actually went down the chromebook route first but then I realized that to get a chromebook that uses a snapdragon cpu, and has a small formfactor, with linux support was actually a difficult combo, and if I did find one, there is a lenvo thinkpad for example, it was like $1000 or so.
