If I were a developer I would wait for PR 1.2 to see if Nokia solve the OVI Store payment issue... nonetheless a good initiative from OP.

As for Khertan's comment, I have to disagree (thank you though for creating VectorMine). I have tried it earlier (not sure if it's a shareware from the get-go).... but found the game not something I would pay for personally. However, I did pay for Angry Bird level pack (when it was available on OVI Store) and I was considering buying Sygic only to find that on N900 it is not that practical because my N900 got very hot during usage. What I want to emphasize is that there is definitely market for N900.. but as you suggested, the user base is most likely different from the iPhone crowd where they are seemly willing to pay for anything remotely interesting.
