The Kindle is being released today.  Amazon have information on it here.

I love the idea, but it looks pretty hideous as an object, except for the paper-like screen surface.  It is ludicrously expensive too, at $399.  I can’t work out if it will load from text sources such as Project Gutenberg, which would be the whole point for me, though probably not for Amazon!
Apple should make one, a lovely one.
