Ken Nielsen

Unmissable. Very well read. A gripping story about a man who became very important to the world. The story shows again (toi me, anyway) that only the truly obsessive accomplish great things. That is not welcome news, but cannot be ignored.
After finishing the book we are left with much food for thought about what will happen to apple and the tech industry.
I am not sure if this book is better listened to or read. Perhaps there are parts that I would have liked to look back at and reread (the main disadvantage of audio book, I think) but I don't believe my experience was much less rich by listening rather than reading.

To me, the above categories are not very useful. We all know of Dickens but, I suspect, few of us know much about the man. After reading this book, we do. And we understand how he became the great storyteller that he was.
Not a great man, not even an admirable man in how he treated his family. Still, for me his novels become more understandable are reading this biography.

The first book I have bought from Audible that I was unable to finish

Very disappointing reading. Two examples: An Australian character is given a very bad cockney accent. Gail, the main female character, is read in a breathy voice that reminds my of Marilyn Monroe in those old films, Gail is a successful barrister! She would not speak like that.
The reading became so irritating, for these and other similar reasons, that I have been unable to finish the book.
If the reader can't do accents and voices accurately, he or she should just read it straight, without any attempt to be in character.

My first serious Audible disappointment. I will need to be much more careful in my purchases in future.
