Cons
Con Limited hardware support
There is a list online of about 100 or so computers that officially support Cloud Ready, but it can also work on a laptop not on that list, results may vary.
Con Only really meant for web browsing
To use the software, you need to have a Google account and log in. Because it's meant for web browsing and researching, you won't find software like Steam, Office, Adobe Photoshop, Aftereffects, etc; or even a 3rd party browser other than Google Chrome.
Although there are plenty of alternative web browser online, and in the Chrome Web Store, which is still supported by Chrome OS.
Con No systemd
Some packages flat out won't work because systemd is non existent, sadly pipewire needs systemd to run. Hopefully Pipewire becomes usable soon. Edit: Pipewire does work but you will have to make a startup script.
Con Few Arch packages might not be available yet
Developers are working migrating all packages into their own repositories while ensuring there's no systemd malware.
