It was hoped till recently, that the coming Zune firmware udate would allow to load ebooks onto your Zune to make your read on the go, unfortunately this has not been done yet. The team at Instructables.com have developed a nice little solution to it. It’s a pretty simple, all you have to do is, grab your self a program called jpegbook.
Once, you’ve downloaded and installed hit CTRL + O to load up your docuent (needs to be a text file) then change the output settings to 320 x 240. Now change the output of the file to a folder on yout PC that is monitord by the Zune software. That’s all!
