It only took about 2 minutes to download Julia Child's book onto my MP3 player. I did it from the test site in the A/V workroom that we were encouraged to use, because we were expecting a download station in our division. That is real convenience, if you have a player other than an IPod.
So, we got the download station, and I think the fact that it doesn't accomodate IPods is slowing it's usage. When it is possible to use an IPod (they said it would be this summer), we might see much more action.
Come try it out if you have a palm pilot or MP3!
