I need to buy a laptop for my daughter for college. She wants a MAC. Fine. But in trying to decide what to buy, I'm lost. I'm used to PC's and Windows based laptops where the more RAM and the bigger the hard drive, the better. Throw in a great processor and you've got a great PC or laptop. But I remember looking at a MAC someone bought long ago when they told me that part of the beauty of the MAC system is that it used memory more efficiently and therefore didn't need as much. So, what do I look for in a Macbook? Is less memory OK? Does she need a big hard drive? Help, please, if you can.
