When comparing Chromium OS vs GNU+Linux, the Slant community recommends GNU+Linux for most people. In the question“What are the best Operating Systems for x86 PCs?” GNU+Linux is ranked 5th while Chromium OS is ranked 6th. The most important reason people chose GNU+Linux is:
You don't have to pay anything.
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.
You don't have to pay anything.
It is a Unix clone.
Pro Many different desktops to choose
Just use whatever you want. Some are lightweight, others are full of extravagant features. There is a flavor for each taste.
Uses the same userland as other GNU variants.
Possibly harms your privacy.
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 Many distributions
There are just too many of them to know.
It's only a clone and some things work differently.
Con Most Distributions are not LSB-conform
The most Distributions don't follow the Linux Standard Base which results in different package formates, package management tools, bootloaders, init-systems or even filesystem hierarchy standards.
Con GNU Copyleft
The coplyleft in the GNU licenses make it unattractive to many developers. It s also impossible to port GPLed Linux improvements to other more open operating systems like BSD or Haiku.
Con Frankenstein OS
The whole OS is mixed together with software from different sources.
Con No interface Guidelines
Since there are plenty of X11-Desktop environments and two big Widget Toolkits, every app works and feels differently.
Con Often limited by decisions of the Kernel developers
Support for the latest features in Linux is often limited by their kernel developers, for example, Nvidia once had added patches to support Optimus on Linux, however, the kernel developers rejected those patches resulting in still no official Optimus support for Linux.
Con Most 3D drivers are not as fast as their Windows counterparts
The only display driver that comes close to their Windows counterpart is the nvidia driver. Both AMD and Intel drivers miss a Control Panel on Linux to adjust more settings than just your resolution they also usually much slower than their Windows counterparts.
Con No graphical user-interface
As the most unix systems this also comes without a graphical user interface by default.
