WOW. I just found this site: the Windows Mobility Marvels is a collection of dozens of webcasts that touch every aspcet of mobile development from getting started to ASP.NET to data communications to security. If you are a mobile developer or if you are a .NET developer interested in mobility this is a must-vists site. Enjoy!
