I get the sense that many people LIKE the Google model of a well made application with free maps and navigation all without a subscription. Right?

I had bought the $200 navigation car kit for the N800 aaaages ago when it was new, and it's been okay (not bad, not excellent--pretty okay) but I PAID for it. This Google model obliterates what I've seen and read about Ovi on the N900 so far. I've been very seriously considering going Droid (if only the memory wasn't so lightweight--but I might willing to forgive that for all its other excellent points).

Why can't the clearly better hardware of the N900 get clearly better navigation? Ovi doesn't strike me as clearly better .. or is it? Help me understand, here. I thought Nokia had their own maps and that this was their own product and their own software. What's the deal? What am I overlooking?
