No, I said the OS didn't look like something you'd use for heavy-duty development work.

I was being a little sarcastic, but I was just amazed at all the people who spent ten seconds looking at this and said "this is useless, it clearly wouldn't be very good for all the extremely complicated powerful things I want to do. Can it handle fifteen different terminal windows? Fail!!1"

I don't actually see any os at all on this site. I see a ui design idea. Hence my assumption that you don't build your s on top of an os.

Or maybe I'm just old and words no longer mean things the way that I am used to interpreting.
