i was originally looking to get the sansa clip 2gb for my 7yr. old.  now i'm thinking it might be a good idea to get one that she can watch videos on.  i'm not very tech savvy but heard the clip is really easy to download music on.  my question is would the fuze be the one to get to watch videos on & have music?  would i be able to download her dvd movies on it & is the fuze also pretty easy to download to?  and would the 4gb be good enough or would i need to get the 8gb?

thanks!
