The problem with the move to ebooks for technical subjects will be the lack of editorial oversight. Tutorials, blog posts and a smattering of example code is fine for messing about with some new technology. But where are the authoritative sources. Looking at my bookshelf now, where are the websites that contain all the information I got from (the excellent) "Mastering Regular Expressions" or "CSS: The Definitive Guide" which sits nicely between the CSS spec and actually being readable. These books still need to be written, in the same format, by the same experts because they contain a lot of value. I agree though that they don't need to be physical books -- all my new O'Reilly books I read in PDF format. (Realise there's a lot of O'Reilly naming here, it's only because I really like the quality of their books. I'm not affiliated with them.)
