I was an enemy of the Kindle corp for several years, but, in the words of John Astin "I am much better now..."
Look, the e-reader is the future. Put it (an entire library of knowledge / inspiration / entertainment) in a sturdy cover inside a dry bag and you are set for many, many hours of use. I've been carrying mine on every wander this year and have had zero problems with it, technical or otherwise. Zero. And I have never run it out of juice.
Yeah, I still have paper books, hundreds of 'em, bookcases in every room and I love each and every one of 'em and I'll never get rid of 'em. But I can't haul all those books around with me. I currently have more than 50 books on my 3G and it's still no heavier than it was when I bought it. It is obvious to me that paper stands in poor comparison to this kind of functionality.
As for the "delicate" nature of the device, well, mindfulness matters; I don't soak my down bag or misplace my pack or lose my stove when I'm out in the weeds either. I'm pretty sure I can handle the important stuff.
'Course a Kindle makes poor tinder, unlike a paperback book, and I expect it makes a toxic smoke too, but I don't burn books anyway. Still, it's not multi-use, or is it? It's not just one book, it's 3,500 books if you want it to be. That's multi-something at least.
Yes, put me down as a Kindle supporter, big time. Just like everybody else who owns one.
