I purchased a new blackbook last month and almost immediately afterwards I came upon a great deal on a 12" powerbook that was mint and so now it is my portable machine that I use to take on the road. So what happened next is I moved my mac mini back to the bedroom to hook up to a hdtv monitor and I hooked up my blackbook to an external monitor and am running it in clamshell mode as my main computer. My main question is if I should take the battery out and save it for when I start using it as a laptop again or should I leave it in and just let it keep trickle charging as needed? Any other pros or cons doing this? I really like it as a desktop ....it is quiet and fast, and it works great with my diamond pro 2070b crt monitor.
