$359 for a kindle? Come on, that buys me about 35 physical books - close to 2 years of reading material. Give me the kindle and 20 books included, then we might be talking.
Still, the XKCD on the Kindle made me really want to try one, if only because of sentimental reasons.
I do consider myself an early adopter. But the current asking price is too steep.
Though I don't know that I would be willing to skimp on everything (like a reader with just forward and backward buttons). When I read PDF files on my screen, I regularly use the search features to zero in on things.
Your statement of "as if it had been printed" is intriguing. So the device would have to have something that you can at least plug a page number into (kinda like thumbing to somewhere that you think might be the location you're looking for). At the right price, I'd give up search if it had this as a minimum.
