It certainly has made me think. (Always a dangerous proposition!) I may quibble about it as an OS. IMHO an OS brings bare metal to life. YouOS stands on the shoulders of whatever OS is installed on one’s hardware. Having said that, it “feels” like an OS. Maybe if I write an app, I may have another thought, or two. Certainly congrats and kudos are in order for an “interesting” implementation.
