Yap, marketing. But marketing is not always a filthy word, is it? It can be "abused", but it can also be beneficial for the mutual understanding between customer and manufacturer. I appreciate open development. I am reasonably satisfied with my n900. But I find it really incredible that turn by turn navigation isn't provided, while provided free on Symbian phones. If Sygic can deliver, why can Nokia not bring Ovi Maps with turn by turn nav free to the n900? It's this nonchalance or indifference (or simply lack of communication in case they are doing a really really really briljant job on the background which requires a littlebit more time than normal...) that is disturbing (as well as the lack of focus in operation systems: Symbian, Maemo and now Meego is the buzzword)

Hardware- and OS-wise, the n900 has the potential to be the " iphone-killer". But it is Nokia's own strategic decision making which fails to deliver (and which fails to inspire).
