a couple of "senior newbie" questions. I just bought an 11" Macbook Air. I saw an ad in MacLife magazine advertising what I'm assuming is an additional external battery called Hyperjuice. Am I correct that the purpose of this unit is to extend the battery life of the computer? They have 60Wh-222Wh modules advertised and I'm not sure which is the one to choose. Can someone explain this to me. Also the staff person at the store told me that I shouldn't recharge my computer until the battery was down to 10% or I should drain it completely before I plug it in to recharge it otherwise I could damage the battery. Is that correct?
