I saw a blip of this at MEDC, and just checked it out myself. How cool! It's like a DevCon for all to share!
Most of it is pretty basic stuff, but if you're new to Windows CE, you should check some of these out! (If you are new to performance tools like Remote Kernel Tracker which I've been posting about, take a look at the Microsoft Windows CE 5.0 Advanced Lab that's on that site.)
