It was said multiple times that heritage of MeeGo/Maemo work at Nokia will be used everywhere else in Nokia products. We've got N900's icons reuse on Symbian first, now industrial design reuse for WP7.

For a company like Nokia it makes sense to reuse what is possible. Sometimes this causes issues for consumers who think that Symbian Anna icons on the screen mean everything underneath is also Symbian but that usually comes with the help of sensationalist journalists who can't grasp a thing.

This reuse of N9 body shell actually makes N9 case stronger -- it will be released because there is now no excuse for not reusing the same production lines, at least from operational perspective.

It will be very interesting to see if UX concepts will be swallowed by Microsoft when Nokia would try to contribute them as part of UX differentiator -- if we believe into the point that only MS is responsible for the software of WP7 platform.
