It would be largely fine, but be careful. Being immutable, a lot of things that you would expect will work differently or not at all. I would not recommend it, but if you’re in for a challenge, it’s not bad.

Correct, but new users don’t want to need the command line for something as simple as installing packages.

Speech to text.

You get a full desktop environment, which is preconfigured, has better connected parts, and includes GUIs for things like settings.

Pretty much anything with XFCE, LXDE/LXQt, Cinnamon, MATE, a window manager like Sway or i3, or probably some others I’m forgetting, will work just fine. GNOME and KDE are the most popular but the slowest, and from what I remember, Deepin, Budgie, and Pantheon are somewhat slow.

That’s a good point. What do you use instead?
