I use my MorphOS machine every day for a little bit of journaling, web browsing, calendar/reminders, ripping CDs and listening to MP3s.
Trying to get a nicer email experience going too so I can use it for that.
As an alternative OS, it's wonderful how usable it is in 2017 for daily needs. When I get up to speed to Arexx, I think it will become even more powerful as I start to integrate different applications to perform common tasks etc.
