Books Not much to this other than the news that the dotEPUB extension in Chrome/Firefox saves web pages in eBook format and either ePub or the Kindle friendly Mobi formats.
It's not perfect. It doesn't seem to like images and the formatting of the eBook does depend on how well the page is coded.
Plus you're advised to use to the "print" version of pages if available otherwise you'll have a document filled with comments "underneath".
But yes, that's a pleasant surprise.
