Ovi Maps is not the only thing which makes Nokia look bad among competitors... I do agree that Maemo openess is a great aspect, but there are things like syncing with Ovi Services and compatibility with Ovi Suite that should be ready by product launch and now don't even have a date to be available!!

Back to Ovi Maps navigation, I would recommend everybody to check Nokia official site for N900. Among its features they clear stated that Ovi Maps has free routing, no word or advise that it don't have voice guidance... which can be a common assumption since even Nokia Maps 1.0 had it. The only way consumers could know it was by researching at forums and reviews!

From my point of view, it is invalid the argument that the owner should had researched before byuing N900 and thus shouldn't be complaining now. By consumer rights the supplier is the responsible for instructing their clients about what they product can or can not do, and I think Nokia lead customers to believe they would have an usefull GPS app (voice guided, turn-by-turn navigation).
