Ranked in these QuestionsQuestion Ranking
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.
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 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 Has Bluetooth & WiFi support
Pro It's a complete port of Android to x86
Pro Open source
Using Open Source Mesa for GPU / Video and presently up to Linux Kernel 4.0.6, with some Kernel 4.1 test builds available from contributors....
Pro Actively developed
Since 2009 the pet project of running Android on a PC by a highly respected developer, has gathered many developer contributions from the open source community...and in 2015 they are still going strong and delivering. Contributors are welcomed and needed for ongoing development work, any donations are accepted.
Pro Stable device support
Runs on more devices than any other available Android on a PC product presently available, KitKat, Lollipop, all open source.

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.

- ASUS Eee PCs/Laptops
- Viewsonic Viewpad 10
- Dell Inspiron Mini Duo
