We already have eink for that though Perplexed.

That depends. eInk is ideal for reading long narrative text, such as fiction novels. It is decidedly non-ideal for reference text with illustrations and tables. In this case, though, I'm going to guess he meant something more along the lines of reading web pages (eInk stinks at that), source code in the IDE, etc., rather than "reading a book".
