Hey Everyone, I am planning on buying my first Mac in the next few weeks. I have a simple question. I am planning on having my macbook plugged in for the majority of the time I'll be using it. Will this affect the battery at all? Will it still have the regular amount of power when I choose to unplug and use it off battery power. I know of some people who have had their laptops constantly plugged in and now the battery doesn't power the machine for long. So, I am just wondering if having the macbook plugged in most of the time will affect the health or power of the battery. Thanks for any replies.
