So i cancelled my macbook order and just wnet and bought one from a micro center in my area...I was sick of waiting. Anyways, I got the standard black with the 80gb hard drive. Here's my question, how come right out of the box almost 20 gb of hard drive space is already spoken for???!!! As I was loading some music on there I checked the hard drive space just out of curiosity and was surprised to find I only had 45gb out of the 74gb available. What gives?
