GPS Navigator with 3D Terrain

After the 3D perspective view, and 3D models of buildings and monuments, it's time for 3D terrain to come to GPS navigators.

That's what Navigon 8100T does: it is able to show you terrain elevation in 3D.

Personally, I don't know if this is indeed useful or if it will only make it harder to interpret the maps - considering you should spend most of your time looking at the road ahead and not to the pretty graphics on the navigator's screen. But if you're a fan of the latest gadget and want to show off your GPS around, this might be what you're looking for.
