You might want to know that shelf content stored on the micrsd card will be lost when you power a Nook ST off or update its software. To be very clear
the epubs will still be there, but the shelf will be empty. Since B&N only
has 256K of memory available for user content on the main memory chip, the
shelf feature is pretty much useless. Its only useful for B&N purchased content.
