Weight: 14 lbs.
Comfort: middling. It's a messenger bag. I think messenger bags in general are just worse than backpacks. They slide around you. And they are either too loose and hit your legs while you walk, or they're too tight and it's a chore to get it over your head. Plus, this one is not super easy to buckle/unbuckle.
Computer: strike one. At 5.6 lbs, plus the transformer, that's a big fraction of the bag's weight. And you can feel it too. Granted, when I travel around the world, I'd have a much smaller laptop, but still, it's heavy! I guess the question is, do I think I'll actually want to program anything while I travel? I'm leaning towards no, which would mean I could cut the bag down to about 8 lbs. That's exciting. At that point (and if it's actually a backpack instead of a messenger bag), I almost wouldn't even notice carrying it.
Shoes: my beat-up clogs are not doing it for me. I ended up walking about two miles a day for various reasons, and my feet hurt for a couple days after. My light-hiking shoes would have worked well; plus, they're waterproof. However, having worn them in India, they're clunky, hot, and awkward in hot places. (and ugly.) I guess the ideal is shoes and sandals, but the #1 rule of packing light is not to bring 2 pairs of shoes. Hmm. I guess the sandals don't take up that much space, and I could always just wear the shoes while I travel... this is still not sounding awesome. Hmm hmm hmm.
