UnOrdinary
I want to add my two cents in here. Chrome OS Flex is really great. But I would personally wait until Google decides if they're merging the two projects ( Chrome OS and Android) because that's where it seems like it's going in my opinion.
I do concur that updating Linux through a GUI is not at all intuitive or reliable. I don't know how hard it is to build a GUI application that just pulls data from the command line. But look at Windows They just got winget and winget's unofficial gui is outstanding, So hopefully that will inspire some future designers
With Android now having a terminal, would there be a future of Android specific package managers?
