There is also the fact that an e-Ink page turn is something of an event, while the TFT
LCD can flick through pages without making it something that you notice.
If you get one like the the jetBook Lite or Mini, you can charge rechargeable batteries
offline, and have a set available whenever you need another 30hours, or more, of
reading time. If you should have neglected to carry or not had an opportunity to charge
up a spare set, you can pick up regular batteries while on the go, almost anywhere.
These ereaders let you keep your ebook library on an SD card (at least one other, well
advertised, e-ink ereader does not).
I would not normally recommend the jetBook Mini as it only supports two formats. The
jetBook Lite supports a great many and even three DRM scams (Adobe .epub/,pdf;
Barns&Noble .epub; and Secure eReader .pdb)
