I’ve had one for about a month and a half and I’m delighted with it. It’s extremely user-friendly once you get the basic knack. Easy to read, and you can adjust the font size, which is important for aging readers, ahem. You can mark passages and save them to a separate file. You can put notes in the margins. You can send pages to your pc. As a friend of mine says, instead of schlepping around pounds and pounds of books, you just put this very lightweight thing in your case, and you can have dozens of books for a total weight of a few ounces.
That’s the book-reading part. The bad news? you can’t figure out, or at least I can’t figure out, what page you’re on in the actual dead tree volume, which makes it hard to use for footnotes. Which is not a problem for most readers, but is for pedants like me.
The online part is also very good. You can get newspapers and magazines, also blogs. And you can access the Net, even send e-mails, etc. So it doubles as a kind of Blackberry. Without the telephone. Or camera.
I think it’s great, i’m not at all surprised they’re sold out through next march.
