Hi Vicrev, yes IGN has fold up maps. They take up lots of space, aren't negligible in weight, cost a fortune, are a bitch to refold in the wind and don't automatically orient themselves to the land (you need dougfitz's skills to do that yourself). Tap the iPhone screen three times and the map orients itself. Like in the land of OZ

MendiWalker, I'm taking my iPhone only. It's 140 grams and fits in a pocket on the waist strap of my pack (and never has to leave there if I don't need it). Its charger, which also charges my headlamp, is 27 grams.
Brierley is 305 grams and the Dintaman book is 403 grams. The iPhone is a GPS, which I may never need; contains every map available for France and Spain, if I'm interested in looking; has a few thousand songs if I want to hear some music (I can put it on at night and have it automatically turn off, if I'm having trouble falling asleep because of noise); it has a few dozen books on it, if for some reason I want to read; I can communicate with the outside world, or look up places to stay and their phone numbers to call ahead; it has a compass in case I follow someone with a paper map in their hands and we get lost;
there is an app on it that shows me where the Sun is on completely overcast days or in the middle of severe weather (regardless of network access) in case I become disoriented; and my family can reach me in an emergency. It's also a camera for both stills and video, and a voice recorder if I want to make notes to myself. I can write, post blog entries... blah, blah, blah.
Yeah, it's a piece of high tech like the packs, sleeping bags, toiletries and clothing that we are all wearing. But having it will remove any concerns that I have of being lost or missing something beautiful, leaving me to enjoy my time, contemplate my life, enjoy all the new friends I will meet, and the people I will interact with, and never once have to use it. I thought about a Camino without technology, but even a rough cloth sack for clothing, walking stick, and leather shoes are technology, and people are already complaining on this forum about old men walking around in their undies, can you imagine if I actually left all technology behind and just walked barefoot in my birthday suit?
To each his own, right?
