Reading speed

This is kind of fun.  It tells you how many words you read per minute, and then tells you approximately how many books you can read on one battery charge of your eReader.  It also tells you how long it should take to read any of a number of books.  For example, I should be able to read Tolstoy's "War and Peace" in 12 hours and 48 minutes.  After my terrible experience with Anna Karenina, no thanks, I'd rather have the 12 hours and 48 minutes.
