Nice that people have options. Setting up a desktop on your own isn't always easy.
I tried COSMIC and was disappointed that it didn't work well on a touchscreen (a common refrain for Linux environments, and a motivator for me trying it out). Then again, it's still an alpha. Would be nice to see improvements there, but since it's from a laptop vendor, I don't have high expectations.
I think it looks good, and seems fairly modern. The settings app would probably work well on touchscreen, but I'm sure many apps wouldn't.
Definitely still in alpha.
I like the idea that it will be a bit more secure, automatically. Security needs to be taken much more seriously. Fedora Atomic means most userspace apps will be sandboxed via Flatpak, and the base system itself will be immutable.
Flatpak needs a lot more love, though. Portals aren't as good as Android or iOS or Windows capability-based permissions yet. Many important apps just request full permissions, needlessly.
