1. I have my PRS-300 for about 3 weeks now, and the battery indicator still shows full bar
( well, it won't be a good assessment actually. I often plug it in to my computer to send ebook to it to check how it looks on it, and if I'm not satisfied I will edit them again)
2. I'm planning to buy PSP charger, but then I discovered that I still have one of my phillips discman lying around and it has charger which is works if you plug it in in the dc plug.
3. Can't really say, don't intend to buy lights, the prs's contrast is really fine that medium lighting will do.
4. Had about 300 books and speed is still acceptable. But then I went wild
to send it some more until 589 books and it crashed until I have to format its memory.
