I was wondering this too. I hope the success of Skype and Canola will show people that developing commercial apps for an open platform doesn't mean giving away the crown jewels. I too would pay for an excellent PIM, and I'm a "free where possible, pay only if necessary" kinda guy.

The open source-only crowd are driving away customers and money from the platform. I would like to develop small cheap shareware apps for maemo myself, but I don't think it would fly, with that crowd around.
