I read a lot of books. More often than not, it's about a book. I need more sort of physical space and intellectual space and quiet to be able to do that. Do you read mostly on an iPad now or reader or do you read? If it's my choice, I would read on the iPad,. Partly because of the highlighting, which is really important to me. partly because I read at the gym and on the train and places that a book is not convenient. For some of them, I've been known to schlep around Manhattan with a thousand page hard-covered giant design book.
