OK I so I picked I don't have an e-reader before I read the comments that you can download one for a PC. But I have to say I would prefer the idea of a real physical book. Yeah I understand the impracticalities of it, but I just like the physical feel of a book. A signed copy is also an awesome idea. The it could go next to my signed Robert Rankin books.
That being said I think a book is an awesome idea and I might even bite the bullet, download teh e-reader and buy the book.
