I'm with you. I have wanted to develop apps for a while, but I didn't want to jump into Java or Objective C. With C#, I already know how things work, so there is no learning curve for me. So I dropped the $99 to sell apps in the marketplace. My market verification is complete, but I was not picked for the initial wave of apps. Hopefully, I'll get cleared to sell WP7 apps soon after launch.
