cucciasv, that is an awesome post!! I LOVE reading about how other people solve their travel problems. I really appreciate that you provided links.
The iPad mini certainly has its enthusiasts. I will have to look into it sometime, but for now, I agree with thisisme, there are practical limits on how much I can carry, and probably will just abandon the iPad entirely and rely on the iPhone and Kindle. It's not just a matter of getting there, but what I carry with me on a daily basis. I may look into one of those eye-fi cards for the camera, because then at least I could upload the photos to the 'cloud' for safe-keeping as I go.
14 pounds for my main bag seems about right. I will just have to keep paring it down. On previous travels, I've gotten to a point where I am just exhausted from carrying too much stuff, and that's no fun.
