I’m back from MIX11 in Las Vegas, which was absolutely awesome. My talk about Windows Phone 7 App Analytics is linked above, but can also be found at its official home on the Channel 9 MIX Event site, where you can leave comments or rate the session.
Regarding MIX in general, I think the updates coming to Windows Phone 7 in the Mango update look really promising. The performance profiler coming in the dev tools update looks really, really cool. I also can’t wait to use the official Kinect SDK when it is released later this Spring.
