I must admit that on my list of "Mobile Device Resources", the "How Do I" videos section of MSDN has always been a bit of a ways down. Imagine my surprise when recently visiting this site and discovering that the list of videos is now at 43!
With the availability of these videos across multiple formats and an RSS feed, this resource has now become a "top-of-the-list" recommendation for both new and experienced developers. I highly recommend taking the time to visit this site today!
