We were able to get upwards of 40,000 page turns with the Kobo Touch with our test fixture. Your total battery life is, as you indicated, a combination of how often you read and also how much other things you do, (including leaving the device in sleep mode because that also consumes power).
I'd be interested in exploring going back to a 'more' absolute measure such as 'page turns' or perhaps something like the mobile phone industry (stand by time / talk time).
