Great question!
Because I have limited needs, just a storage device with basic streaming capabilities, I use HexOS on the daily - mainly Plex. However, this is just part of my larger effort to build out a home solution that will eventually replace paid-for services that have increasingly risen is price and are more inclusive of advertisements (I LOATH ads with a perfect hatred).
I am attempting to time my efforts with HexOS maturation. Which is to say as HexOS gains in features, I look to increase my DIY replacement of paid-for services.
I know not everyone has the same timeline, level of effort, risk tolerance etc.. as I do, but that's why I jumped in early.
I keep backups, try to contribute to this community and help where I can to see where this is going.
