I finished reading this biography of Steve Jobs over the xmas holidays. Thoroughly loved it.
Served my geek tendencies as well as a really interesting story about the formation of Apple and the man behind it - he really wasn't always a nice guy, but he was always passionate about doing what he loved.
Highly recommended!

I read it on the kindle reader on my iPad 2, the first real e-book I've read from start to finish. I think I'll buy most of my books in e-book form from now on.
