I need a new laptop for school so I decided I would try for the first time a macbook. I was hoping to make this a computer I can use for everything. I was going to get the 13 " MBA with 8gb ram and 512gb flash SSD. My school starts end of January so I need to make a decision relatively soon. Should I wait the 4? Months until it has broadwell or is it not going to be that much of a difference and just get the current model. Thanks for helping
