That a). Drive and Maps survives and b). that it's ad free.
I recently swapped my Samsung Omnia 7 out for a Lumia 800, and think that those two apps are Windows Phone's defining cornerstones. Drive for the obvious offline 3D navigation. Maps because it does places better than Bing Scout. And the UI is breaking ground (tiles in the pull-up menu - why hasn't that been thunk of before)?
As for the focus on handsets - can't speak for the 710, but the Lumia 800 is quality. I originally got the Omnia after extensive checking out of the competition and because of the AMOLED screen, but the build quality is, like, streets behind the Nokia.
Looks like the fires on the oil rig are being put out, slowly.
