I don't understand who this is aimed at, or what problem it intends to solve. Is it supposed to be a fully-featured operating system or not?

That makes two of us. Apparently some pretty screenshots and vague, meaningless fluff is enough to get to the front page of HN.

As best I can tell, it's a GNOME skin.

Didn't I download an install this exact OS a year or two ago? I don't believe they've changed the website, or the OS, in any significant way since then... Not exactly sure why this was posted or how it made front page :|

Oh, and I didn't keep it, can't even remember why (probably because it was just another boring linux distro with nothing particular to offer)

So they ripped off the OSX UI completely and then changed a couple of things?

They did a better job of ripping off Apple's web site. Impressive commitment there.

I'm so tempted to be snarky as Elementary OS seems to be reinventined everything. But you know what, they seem to be doing a very elegant job of it. God knows that even Marlin in its very unstable state is a god send for the person whose been using Nautilus for the past N years.
