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 Difficult to install on non-free hardware
Unlike Debian, Devuan offers no unfree netinstall media, so if your system needs unfree drivers (e.g a laptop or a tablet), you'll have to download the Debian firmware on a separate USB.
Con No systemd
Con Fragmentation
Forked distributions like Devuan and Artix fragment the Linux community and hurt the original project. Debian users who do not want systemd should use Slackware or BSD instead.
