did you ever think the only reason nanos don't play video is because movies are too huge to put on a 4gb disk? they could put the software of a normal ipod on a nano any time they want, but a nano just doesn't have enough space to put as many movies as you feel. and think about it, the average .avi full length movie is 700 megs. that's a lot of space considering you have 3.3 gigs left.
