what people are forgetting is Ovi store is already a success if you minus the Maemo version, they get over a 1.5 million downloads a day.
I'm pretty sure Nokia will put in a massive amount of money and other resource's for MeeGo version of the store now the MeeGo platform will target a much different and bigger user base.
I'd be happy with a bookmark to Extra's Download Page on MeeGo devices, then if people see something they like they will click download link and Repo will be configured and added automatically with no hassle.
