If I got a portable dvd player that got about 3 hours battery time, I'd have to buy 4 extra batteries for it to work for the entire flight. Wouldn't that be a little pricey?

I am seriously considering the powerbook 12", I was hoping that it would have gotten a bigger upgrade on Wednesday but I'm still thinking about buying it. Does anybody know if most airlines have power ports in Y? I guess I've never looked. I fly mostly EVA Air Evergreen Deluxe, I'm heading for their website right now to see if it says anything about power ports.

Thanks for the replies!
