Hmm, admitting to that, could get you in jail ... couldnt it?
Well, i know several illegal sources on the internet, to obtain ebooks. And i have to say. I have downloaded a few. At the moment, i am buying books in paper form and download them for reading them on my iliad. I know, thats not legal, but i have to say, thats fair use to me.
Started reading "Moving Mars" from Greg Bear as pbook, then got the iLiad and continued reading there. I have "Wheel of Time Book 11" as hardcover on my shelf for quite some time now, but i will read it as ebook on the iLiad. And thats the same with several other books. (China Mieville, Perdido Street Station e.g.)
So even if it is illegal, i will continue to do it like this. Because i paid for it, and i could make a digital copy of my own, if i wanted to, and purchasing ebooks legally costs almost the same as the pbook and doesnt even give you the advantage of reading it on the device of your choice.
If that makes me a criminal, then i guess i am. (though a charming one

)
