Slate has an article about Sony's e-book device "E Ink". While the author says that the device is easy on the eyes, it is very limited in functionality:

The biggest problem with E Ink is that it has a very slow refresh rate—around a second to turn a page. Though that doesn't sound like much, it's quite a pregnant pause: Clicking through the Reader's menus is tedious, and page turns quickly become a bore.

The Reader works well for plain-old, front-to-back reading. As long as you don't do a lot of flipping back and forth, the device won't let you down. But it doesn't have a search function, nor will your book's index or table of cont...

The biggest problem with E Ink is that it has a very slow refresh rate—around a second to turn a page. Though that doesn't sound like much, it's quite a pregnant pause: Clicking through the Reader's menus is tedious, and page turns quickly become a bore.

The Reader works well for plain-old, front-to-back reading. As long as you don't do a lot of flipping back and forth, the device won't let you down. But it doesn't have a search function, nor will your book's index or table of contents be hyperlinked to the pages they reference. So, ironically, it's significantly easier to find information in a paper book than in its digital equivalent. Sony's e-content is also read-only: You can bookmark a page, but you can't add marginalia.

Sony is stopping at books, when it should be making a device that allows people to curl up with all of the written content that's currently stuck in their computer, as well.

Amen to that. The e-book revolution is still on hold.
