I want to literally get my hands on a Kindle and feel it (I've seen lots of them but never held one) to see if really has worse build quality than the flimsy NST. (I own an old but sturdy Sony PRS-505; other than wishing it were as fast as the recent Kindles or the NST, I have no complaints about it.)
