The other problem is how you get people to pay in a system that doesn't support DRM.

We have already seen serious issues with paid apps in the ovi store: the 'angry birds' levels pack was pulled after less than a day once it was pointed out that although you paid if you went through the Ovi UI, if you did it via the terminal, you could d/l it for freee - and that's before people start file-sharing. Then there's a sounds fuile in Ovi that you can buy but not play (since it's a DRM file).

Nokia/ovi need to sort that one out before they can begin to attract paid apps.
