I recently learned about a product called a Zimaboard, which to my understanding is like a raspberry pi, and the default OS on the listing says that it comes with CasaOs. Doing a quick search, I found the website and tried their demo, which had a very modern look with many popular apps available and so I got curious as to why this wasn't as popular as other server os.

I want to know if any of you had a go with any of these things and if you have some experiences or opinions regarding it.

It's very modern looking UI gives of "Apple" vibes which makes me trust things less, but that's just my caveman brain acting up, hence the reason I'm asking.
