Well, I've never carried a spare laptop for my personal MacBook Pro (15" non-unibody), nor do I carry one for my work Thinkpad. I'm never that far away from a power point (even taking into account the hopeless battery in an X61 Thinkpad).
If people really need more power than the sealed battery in the 17" MPB, then I'm sure some enterprising 3rd party will come up with an external battery pack that plugs into the MBP's MagSafe power port. That way you'll be able to charge both your batteries at the same time, and the external pack won't take up any more space than carrying a spare. And you get a primary battery that lasts 6-7 hours.

What's there to complain about?
Paris, 'cos she likes battery powered stuff.
