With Catalina, I'm also not seeing any major benefit to upgrading. The features list is thin and no 32bit programs kills a lot of random stuff that I can't find a quick replacement for. This is the first time I'm not upgrading macOS in 15+ years.
Unfortunately if you want a good keyboard, you don't have a choice - new mbps can't downgrade lower than catalina.
The keyboards are mediocre at best anyway. My MS sculpt is the best keyboard I've used and try to bring it with me even if I'm just using my mbp as a laptop
I love my new Lenovo laptop and it has a great keyboard. There is a choice.
I'm still running Mojave on my desktop (iMac 5k.) I have the occasional 32-bit, obsolete app I run, and don't want to deal with the upgrades right now.
There's Apple Arcade for one benefit
I haven't heard of that! But it sounds like it might be game related, so I probably haven't found it due to lack of interest.
