I would take it - I've taken mine on the last two trips I've had to do to different states. It saved my sanity on an eight hour Greyhound trip.
One downside though - I keep having people ask me what it is, and a million questions because they've never seen one before. I like spreading the word and convincing people they need a Sony and all

, but it can get annoying when all you want to do is read and they keep asking questions.
