I wouldn't go as far as say "you're pathetic" if you buy an e-book, but it's true that you can find all the same information on the net... however, sometimes it's difficult to find all the information neat and organized in the same place like you'd find in an e-book, so instead of visiting hundreds of sources and go through the trouble of putting together all the information yourself, you can get an e-book that someone has already gone through all the trouble.
But that still doesn't justify buying the e-book, because if it's online, chances are someone bought and already has it being distributed on a P2P (*****, etc), so you can get it for free anyway.
Edit: Why is the forum censuring K-A-Z-A-A? What's the point?
