firstly, a huge thank you to everyone here at macrumors. I have just made the jump from PC to mac, and you guys and your knowledge has been absolutely invaluable in getting started. i have just bought a macbook 2.4, and want to keep the battery as healthy as i can for as long as i can. i have read all the info i could find about cycles etc, but what's the best way to "use" my macbook: connected to the mains all the time, or charging and then using up the battery? would leaving my macbook running on mains mean that i never went through any cycles?
