I don't get it. What's the business idea? It seems crazy to launch a new OS for an obsolete computer model that has not been sold since 2004. And which did not sell in enormous quantities then either. Especially since the new OS does not appear to better then competition in any way.
What were they thinking? Something in the lines of... hey, there was this obsolete computer that we sold a few of in -04, how about making a new, but old-fashioned, OS for it?
