I bought an 80 gig 5th generation Ipod Video, it's the best thing I have bought in years.
I have several hundred cd's and about 500 to 600 LP's which fill it nicely, but it's main use is for Podcasts.
I listen to, or watch podcasts almost every day, now I don't need to put up with sport or fame filled TV, I can watch a 50 minute programme about Photoshop or some other educational material when I want to.
I know that I would have been annoyed if I had bought a smaller Ipod just for music, then later found out how good it was to subscribe to podcasts and not have the room for them or the capability to watch them.
