It is indeed ridiculous and shameful what Nokia gave us with Ovi Maps on the N900 until now. I would fire the team (and yes, I'm a manager in software development). The concept is wrong, the design is wrong, the implementation sucks. Complete, utter failure.
OTOH, Ovi Maps 3.0 on the N82 was fantastic.
Just think what they could have done with the power, space, screen, touch interface and integration possibilities of the N900. And all the map data they own. It just makes me wanna cry.
