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 Rolling release
The distribution is continually updated, so there's no need to install OS upgrades by hand.
Pro Stable
PCLinuxOS is designed around stability.
Pro Multiple desktops available
Mate, LXDE, and KDE desktops are available.
Pro Can remaster the boot DVD
PCLinuxOS has built in tools for remastering bootable DVD into a copy of current install.
Pro Excellent hardware compatibility
Comes with nVidia drivers out of the box. Important if the PC has an nVidia chipset. Most Debian based distros don't have nVidia drivers available at install time.
LXDE version works well with older hardware.
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 Installation fails most of the time, error messages, and hard to go to full screen in virtual box
Con Uses RPM packaging system
Uses the RPM packaging system with APT, rather than the more popular DEB packages.
