I just bought a Zen Vision W and I am in awe with it. I could play most of my downloaded videos in divx and Xvids and the screen is damn clear. Just loaded some movies like Snakes on the Plane and Hot Fuzz on the player and its playing very well. I also bought this for the memory card backup feature. As you do know I shoot with CF cards and this little bugger has a CF compartment to import all my photos into the 30GB drive.
Very happy with it and still trying out the new toy. :)
