Pros
Pro Safe and requires little to no maintenant
Since you only have the browser, you cannot install applications (outside Chrome Apps which are decently protected by their limited API and the Chrome Web Store). This means no harmful virus, and also nearly no way you can screw your system. Everything will just work.
Pro Minimalistic interface
Chromium's system UI uses as little screen space as possible by combining apps and standard web pages into a minimal tab strip: While existing operating systems have web tabs and native applications in two separate strips, Chromium OS combines these, giving access to everything from one strip. The tab is the equivalent of a desktop application's title bar; the frame containing the tabs is a simple mechanism for managing sets of those applications and pages.
Pro Lightweight
Because Chromium OS is designed for users who spend most of their computer time on the Web, it is intended for use in computers with little local storage and fast boot-up times.
Pro Focuses on KDE/Qt Apps
comes with none GTK apps per default
Pro Independent from Arch
its not just another Arch Spin-off
Pro Keeps Gnome apps tidier even than Gnome distros
Cons
Con Google
Possibly harms your privacy.
Con Made for developers
ChromiumOS is mainly made for development, so there exist no official install images and you have to build it from source or use third party images like Arnold's or the waterfall images.
Con No auto-upgrade (unlike Chrome OS)
Chrome OS auto-upgrade the system, but Chromium OS does not. It's possible that they're thinking about adding that feature from the design doc.
Con Weak base
Sometimes updates will not execute hooks(full update always misses to run mkinitcpio) so you get an unbootable system.
Con Small development team
The team is very small
Con No real installer
Has no installer just a big bloated LiveCD that gets unpacked to your disk.
Con Pacman
Compared to deb or rpm it takes ages to update the system, it's also very dumb in dependency tracking.
Con Unreliable Servers
The CCR or the community forums are often down or unreachable.
Con Overwrites your default EFI config
It overwrites your default EFI config wich can make you PC unbootable if something goes wrong.
Con Uses systemd
Which is very hard to debug and not a *nix standard.
Con Only available for x86-based CPUs
Con Wont let you install the system to USB drives
Chakras weak installer Calamares does not allow you to install it to a USB drive.
Con Weak update process to a recent release
For example, you can install the Goedel Release and update it to the current release which then fails to boot due to some systemd-errors.
