I've folded and got one (arriving as a birthday present). Like my Ipod it'll be a useful thing when I'm downroute or deployed and I can carry loads of books in a fraction of the space.
I'm thinking for big reference tombs.....having the solid paper copy is preferable. (though they are big and heavy) but for most of the smaller campaign history and non-technical history accounts...an ebook reader would be preferable now. Thats what made my ex-library explode over the past 10 years.....books covering campaigns and aspects of militaries from the Spanish American war to Korea. Many of them were one off reads but would be useful to have around to reference for specific factoids.
