For interest, this second hand iBook (500MHz/256MB ram, 18G HD, (c) 2002 on the bottom, does that mean it's a dual-USB? I get confused...) gets about 2-2.5 hours per on charge. I try to charge it fully and not let it sit on the charger, but cos I use it at work as well as home it tends to get two cycles a day these days. Original battery so far as I know... No noticable decline in battery life since I got it eight months ago; though I found the "sleep the book and take the battery out for a moment" trick doesn't work on this machine!
