That wasn't ever in doubt. That's also not the relevant piece of information - people looking for a summary want to know why the thing is worth paying spending time on, not random attributes
You do realize when you say that you do assume they know it's an OS and by that you effectively have to regress into using the same level of argument as me just like how I assume they don't know it's an OS, right?
That doesn't tell me what it is in a concrete sense. Must be hundreds of OS that run on similar hardware - what makes this one different?
