The 80 GB version of the "
iPod classic" may not be Apple's most capacious model, but you'll still have to do a whole lot of downloading to fill all that space. Once you have the
iTunes software
installed on your PC you can browse through the iTunes store (from inside the iTunes software), where you'll not only find all the latest (and oldest) tunes from your favorite artists, you'll also find a huge selection of free podcasts and videos available for download. Quite a few big-time colleges are now publishing videos from classes covering just about every imginable topic - and all for free.
