As a Flip Video Camcorder user, I love my Flip Ultra and Flip Mino video cameras, especially the Flip Video HD Camcorders, pretty easy to travel and shoot. But I hated the fact that Windows Movie Maker didn't play nice with them. Anytime I went to view or edit a video inside of WMM, I'll only get audio and no video.
