Kindle was released today, the e-book reader from Amazon. It has nice features, like wi-fi connectivity so that you can instant buy from amazon. It's slim, it's light, and from what I have seen looks nice. It looks like something you can hold as easily as a book. I look forward handling one for real. I've watched a few videos of the thingy, but no where I see features like underline, or capabilities to insert notes - are those features just a given, so this is why they are not talked about? I'm assuming the keyboard is for more than typing urls.
Update: So yes you can have annotations, and underlines and the ability to export them. This is extremely useful, as right now I need to go through the books and the underlines and write them on paper as book summary, which I only rarely do, which means I don't get as much value out of the book itself. So I want one!
By using the keyboard, you can add annotations to text, just like you might write in the margins of a book. And because it is digital, you can edit, delete, and export your notes, highlight and clip key passages, and bookmark pages for future use. You'll never need to bookmark your last place in the book, because Kindle remembers for you and always opens to the last page you read.
