e-ink is the display technology used in all the black-and-white readers. Very cool stuff, it only uses power when it changes. So the battery life on readers is absolutely ridiculously long. It also reads like paper, which is why it's a different experience reading off a reader than a tablet with an LCD screen.
The floundering around is being done by the publishers, I believe. The fact that every reader manufacturer wants to be the next iTunes is a royal pain in the butt, forcing a bunch of competing and incompatible DRM on the market. Imagine if you could only watch Sony DVDs on a Sony TV, not on a Toshiba. That's pretty much what we're dealing with right now. Actually, that would be better, because I could loan my Sony DVD to a friend that had a Sony TV.
Our local library is trying to get the ebooks working properly. They've used a couple of different providers for the books. Some of the restrictions are retarded - there's no reason why I can't check out a book at the same time as someone else when it's just bits. A bigger problem is that they tend to offer a lot of series, but only books 2,3 and 5 for example.
