I've never had one before and was wondering something. I have quite a few music videos that I've put together. What would be the best thing to put them on so other people can gaze in their glory?
put it on the internet. or you mean like something you can take with you, to lets say school, and show all your friends. well then out of those you listed i guess it would be the video ipod. or if you have a psp.
It all depends on what else you'd want to use it for. Many can use all the features of a pocketPC, some like the mp3 playing on a media player. They all can play video, but it's up to you on what else you want to use it for.
