I am very, very sad to hear the news about Steve... He was very kind to reach out to me as I became CEO of Google and spend time offering his advice and knowledge even though he was not at all well. My thoughts and Google's are with his family and the whole Apple family, wrote Google CEO Larry Page on his Google+ page.
