Is it just me or this article outlining the most natural path for any Linux desktop? Rather then chase the general consumer, focus on your core audience who is already using your OS for the server.
Not only is it a more natural customer base, but you also have an advantage by eating your dogfood. GNOME devs would have 1st hand knowledge of what works and what doesn't for engineers and developers. And this sort of domain knowledge is gold when it comes to designing good interfaces.
I would love to see this effort happen, and might even go back to Linux if it really created something great.
