Later this month, I will be taking a flight on Air Canada across the country to St. John's, NL. With the stop in Montreal, it's a 8 and a half hour flight. What do you people do for long trips on planes? The plane I'm going on has an entertainment system on it, and I'll be bringing my laptop, but the battery is limited on my little Aspire (although I'll most likely end up bringing my MacBook, but it probably won't last through the first connection). I have lots of iTunes content, but I've seen it all. What are some suggestions to stay entertained?
