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 VERY small
Can be as small as about 9MB, and with even X, wireless modules, and more, it takes up only 72MB.
Pro Surprisingly customizable
Fluxbox window manager is especially slick looking all considered, and the options one gets with it's toolbar, app bar, and wallpaper are surprisingly complex for such a small distro.
Pro Use of tcz packages stored on media outside of MyData
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 Not visually appealing
The operating system is not very pretty.
Con Can be somewhat slow to turn on
Once it is up and going it is unrivaled in speed, but it can be sluggish when it comes to turning on, restarting, or turning off.
