I knew that you can put simple texfiles on your iPod (called Notes), but what I was completly unaware of was that iPod recognizes basic HTML for linking. You can not only link between notes, but also to songs, pictures and maybe even videos.
This open the possibility to place miniature websites on your iPod, called podSites
I came stumbled across this name on a blog, but a quick search on Technorati showed that podSites has been around for almost a year.
