I don't see how this helps. I travel a lot and often on long plane journeys I go through 3 batteries with my MBP.
Huh? I routinely get 5 hours with my MBP. If you need 15 hours of battery time, then you must be on round-the-world nonstop flights (considering that you can't turn your computer on until you're well into the flight and have to turn it off before landing and allowing time for sleeping, eating, and going to the bathroom).
Fine if you can get one. You'll find that on many airlines you'll only get a power socket in first class, particularly if you are travelling outside the US. Sometimes you don't even get one in first class.
Then stop flying Ryan Air.
American offers power sockets in almost all first class seats and most coach seats (except for commuter flights which are never over 3 hours). I don't know, but I suspect that most US airlines are similar.
And if you're a regular enough flyer to be moaning about this, then you'd be exec platinum on American and sitting in first class, anyway.
Yep... Quite right.
I've flown on as long of flights as you can get in the United States, and I have absolutely never (and I mean never) been on a plane with something I could plug a computer into. No power taps anywhere.
Either you're flying Podunk-air or you're misinformed.
Go to seatguru.com. I looked at American Airlines since it's my preferred airline, but you can check any airline.
On American, every single plane (except commuters) has power ports in coach. Not at every seat, but if it's important to you, it's trivial to see which seats have power ports and ask to be seated there.
I wish people would stop making complaints that are just plain wrong.

Name one major airline that has no power ports in first class. Then name one that never has any power ports in coach.
Then go to seatguru.com and see how wrong you are.
(Commuter planes excluded since they almost never fly over 3 hours).
Not usually.
With the first several batches of the MacBook Pro, they were quoting in the 4+ hour range. But, users were frequently reporting that in their most conservative use that they could only get between 1.5 and 2 hours at the most. Some were even getting far less than that with no resolution being provided by Apple..
I guess I got the good one, then. I get 5 hours on my 17" MBP.
