Microsoft has a video that discusses the differences between Windows CE, Windows XP Embedded, and Windows Mobile. It also includes Windows Embedded for Point of Service. The video is 48 minutes long and includes some demonstrations at the end. Unfortunately for me, my kids interrupted me right before the demos and I accidentally clicked on stop instead of pause. As far as I can tell, there is no way to skip to where I left off and I don’t have time to watch the video from the beginning again.
