This is one of my eBay buys, I don't remember when I got it but I've had it for quite a while. The battery only lasts me 15-20 minutes at best. Also it has a distinct smell every time I open it, but I'm told that's a normal thing for iBooks.
Mine runs OS 9.2.2 and 10.4.6 (I never got around to updating it). I upgraded the hard drive from the original 40GB drive to an 80GB one, though the process of opening it and the heat from these hard drives caused some nasty cracks in the aging plastic.
