>>This is really 'cool', but I dont know if this kind of desktop can bring a better productivity or really help novices to take on on computers. If novice have problems to catch how to use a mouse in a flat 2d world, how they will be able to handle this 3d world?

Thanks for the link.
I have downlaoded and test this app.
But this is not the same thing as the looking glass project.

Looking glass is an integrated desktop AND os environment in 3d for apps and windows.

3DNA is a shell with a 3d space where you can put shortcut to lauch apps.
There is no productivity features in this product, just an eye candy :)

Have you take a look at the presentation?
