The Way Of Kings is actually what made me buy an e-reader, after I learned that this thing had over 1000 pages. Only afterwards it turns out that I can not actually obtain it legally because it's not being sold for users in Germany.
I have his Mistborn series in good old paper, and his new book not at all I'm afraid; but on the other hand I got my hands on some great books from Smashwords which I wouldn't ever have touched otherwise
So in the end the ones who sell their books without restrictions, are the winners, at least that's where my money goes now.
