Turn your iPod into an e-reader

Last night, I discovered the "Notes" feature on my 4th generation iPod Nano, which effectively lets me turn it into an e-reader. With the help of this website (or this one, which does the same thing), you can turn pretty much any text file into a series of notes files that can be put on your iPod, complete with hyperlinks from one file to the next. It's very cool.
