On his blog, Allan Day has posted an overview of GNOME OS with a description of what it is (and isn't) based on discussions at the recently concluded GUADEC. "Many of the things that we want to do as a part of GNOME OS are old ideas that have been around in the GNOME project for a really long time. The aspirations that are driving this process include things like providing a better experience for application developers, automated testing, sandboxed applications and broad hardware compatibility. While each of these goals could be pursued independently, there are enough interconnections between them to make a holistic plan worthwhile. Yes we could call the initiative something else, but GNOME OS has stuck, and it kinda fits (as I hope to explain a bit better below)."
