To the OP--it's obvious you're going to get more than a few opinions on this. Everyone has his or her own traveling style and packs accordingly. I lean toward the fewer electronics approach--there's little I enjoy on a bike tour more than getting away from the phone. As a result, I carry no chargers and no spare batteries--nothing's that important that can't wait until I can buy them at a store. But not everyone sees it that way. There are bloggers and professional photographers and those who keep a business and/or family supported while on tour. And there are information addicts as well, I guess. You choose the trip you want/need, and gear up (or down) for it.
