Your poll didn't differentiate between reading for pleasure and reading for work. For work, I read 40-50 books, sometimes more, every year. These books range in size from 150 printed pages to 2,500 printed pages, with most coming in between 200 and 300 printed pages. (It's a tough job being an editor and having to do so much reading

.)
[EDIT: I missed your sentence that said excluding work -- sorry about that

For pleasure, I read between 100 and 150 books a year. Again the number of pages varies. I am not sure how to count the pages for you for the books I read on my Sony 505, but the books I read on it are generally read in 2 to 3 days. The other books I read for pleasure are hardcover books, which take longer, primarily because they are what I read beore going to sleep. They vary in length from 350 to 2,000 pages, with most (95%) falling in the 400- to 500-page range.
However, this can be a bit misleading. Of my pleasure reading, probably 75% is done on the Sony 505 and consists of pure entertainment books, that is books that are pleasurable to read but then can be forgotten. Over the years, I have found that pure entertainment books can be read fairly quickly whereas books from which I wish to retain knowledge require a slower and more analytical reading style.
