E-Ink?
E-Ink sounds pretty cool but I bet it's nothing like I imagine lol. I thik reading from an LCD screen would be annoying. I personally prefer paper books and don't intend to buy an e-reader.
The cheapest one is the borders one which is about £180, which is a fair price, but will obviously be an LCD version.
I wouldn't enjoy reading a book on my computer screen so I really don't think i'd enjoy reading a book on an e-reader with a much smaller display.
Once they come down in price, or if somebody who I know buys one, maybe I will be converted, but for £400+ for the ones which are aparently decent I will have to pass (for now)
The fact most older books (which are some of the best) can be picked up used for a few quid (Example Hardback version of Abarat by Clive Barker for £1.99 used). You really save a lot. I only read one book at a time personally (when reading for pleasure) so being able to Carry 100 books isn't really useful.
But the nay-sayers should consider the amount of shelf space you could save. To me that would be the biggest advantage. I'm personally a fan of digital content, when I know it should be available to me for a looooong time. (Example Half-Life 2, Counterstrike: Source etc on STEAM aren't going anywhere anytime soon)
If there we DRM free downloadable movies, or somewhere in the UK you could rent a movie by downloading it and watching on the TV via HDMI I would pay for that. You would obviously need some form of DRM for rentals.
Kinda went off the point a little, but think I made some okay points lol.
