As a man with multiple Chromebooks, I must say I am more than a bit unhappy with the long delays in the releases of both beta and stable builds of Chrome OS, as well as the lengthy times for the new releases to actually become available for download/update. Yes, I know many many Chromebooks are out there, and they must be careful to release quality software updates, BUT it can be extremely frustrating at times.
