Not really, I think that WP will have a bigger userbase than RIM and I think that a better to compare against Android. I also assume that "phoneapps" will work on desktop/tablet windows 8 as well... But again, this is just my thoughts.

I think you're being extraordinarily optimistic. The latest numbers I could find quickly[1] show RIM with more than double the share of Microsoft, and with both showing a reduction in share vs. six months prior. You might be able to claim that people are abandoning RIM faster than they're abandoning Windows Phone, but even that is arguably because RIM is falling from a higher initial position.
The other problem is that .NET makes no sense for mobile apps, because neither of the two largest mobile platforms have good (if any?) support for it. Everyone who is not some kind of Microsoft evangelist is going to support Android/iOS first, which means they're not using .NET and are not going to worry about a Windows port unless Windows Phone gets enough share to be worth worrying about.
