Holy negligible weight, Batman! This Fujitsu e-Book reader weighs so on this side of nothing, it's hardly heavier than an actual piece of paper. Hell, it's lighter than most paperback books.
Hopefully structural integrity was sacrificed too much in making this e-Book reader so light. Because even though e-Books have the word "book" in it, they don't take well to being folded in half.
