The reading experience is pleasant, natural and nothing like reading a computer screen.

Also to note:

[O]nce those microspheres have formed the image of a page, they stay put without consuming any power. Amazingly enough, that means that you don’t have to turn the Reader off, ever. When you’re done for the night, just lay it on your bedside table; the current page remains on the screen without draining any battery power. (According to Sony, one prototype Reader in Japan has been displaying the same page for three years on a single charge.)

But you've gotta have a lamp (or other source of ambient light) to read the thing.

note to self: may be worth exploring for period of winter travels
