I know this is kind of little late but chrome os beta channel has been updated to release 20. What I have noticed with this release that it is fast, and I also noticed that there is still the problem with wifi connectivity such as wifi disconnect when browsing the internet. I noticed that scrolling is kind of jumpy but it is still smooth. But all in all it is still a great update, and if anyone either on stable or the developer channel you can upgrade to this release. Stay tuned for more information and thoughts.
