The development experience has been extremely good. Visual Studio + Expression Blend is perfect for rapidly prototyping apps and fine tuning animations.
As for downloads, I've found it's a lot easier to get your app noticed in the smaller marketplace. Also for a while ad revenue was very good. I made $50/day using PubCenter for ads in my games for a few months. After March 2011, however, something in the system changed (or maybe advertisers just started paying less) and my eCPM has dropped a lot.
