I'm not too keen on the screen's way of blacking out in order to refresh/turn (I don't like things that flash in my face) and my husband wishes e-readers would pre-render the next page so turns go faster. Still, it's a nifty reader and weighs less than the comparable books would.
I'll tell you after the trip how it holds up.
We chose not to get the optional holder. The reader's pretty robust and the reading screen's fairly small and, since it's e-ink, smudges don't show up that well.
