Thanks for the feedback.
Neuroanatomist, I did consider the Hatchback as a gear pack. I really like that bag. It actually might be my second purchase to whatever I get to travel with. I do fly in the US frequently with my camera, laptop, and a few other things. I've been carrying the LowePro Photo Sport 200 nearly everywhere I go. It's a decent hiking bag that works for flying too. It's not the most comfortable of straps though. I've even sent feedback into LowePro hoping to see something with a little better system similar to an osprey pack coming out soon.

Black_Dog, I looked at the Outback 200. It looks like a good pack, but looks to be very dedicated in it's layout. It also screams a little louder "I'm carrying a high end DSLR with some lens....rob me". If I wasn't going to an unfamiliar territory I'd consider it, but I need something that's a little more inconspicous.
