I just ordered my first ever Mac computer the other day. The SR MBP base model. I've read through some of the battery info threads, including how to break it in, etc. The only thing I'm confused about is the best way to maintain a healthy battery. Typically, with laptops, I keep them plugged in whenever possible. So whenever I'm at home or near an outlet, I am always plugged in. Is this healthy for the batter? Or should I let the battery completely drain every now and then?
