Use Macbook Pros with 75 watt airplane power ports
Authored by: cyberdave on Sep 16, '09 09:47:28AM

My 2008 15" MacBook Pro came with an 85 watt power adapter.

My sister just purchased a new 2009 15" MacBook Pro and it came with a 60 watt power adapter, which surprised me.

Checking the specs at http://www.apple.com/macbookpro/, it seems like the 13" comes with a 60 W adapter, the 17" comes with an 85 W adapter, and the 15" comes with a 60 W or 85 W adapter (my guess is this is based on the CPU speed, with the faster model needing the beefier power adapter).

I would think not processor related, but video card related. The new 15" entry level has integrated graphics, whereas the others have a dedicated card. My guess is that the video card is the difference. Your point, however, is still valid, and probably factors in as well.
