I have the original book. I have seen the new edition has been in the process of being published for some time now. Now that it is out, what is new? Is it worth it for me to shell out $50 for the new edition if I have the older one, or are there only minor updates? I plan on trying to find it in a bookstore and looking up info on the publisher''s site, but my search so far online hasn''t been helpful.

I have the original version as well, and while it''s a good book it seems kind of dated now (I got a used copy a few months ago.) I think a more up to date version would be nice, but I haven''t got a chance to look through the book yet.
