My biggest objection to an e-reader was that it wouldn't feel like really reading a book.
Turns out, it does. There are other issues, as as concern about reading, say, in the bathtub. And I still need to figure out how to transfer stuff to my Kindle when I don't buy it at the Kindle store. (I.E. project gutenberg stuff) but the instant gratification of "ooh, I want that book!" and two second later, having it RIGHT THERE in my hand is a huge draw.
