I don't have a light on it, nor do I play games or use the wireless (or if I do, it's only for about 5 to 10 minutes every 2 days), so I wasn't sure.

I got one solid month out of it reading about 4/5 hours a day. I think, however, that it would be fairer to post battery life in terms of hours of reading (with wireless on and off) rather than weeks. Reading 8 hours per day isn't the same thing as reading, say, 2. :)
