My friend has finally seen the light and is switching to the Mac world! He has decided on the BlackBook, but he is stuck on the customize page. He would love to cram 2 GB of memory and a 200 GB hard drive into it, but he is concerned that it may run too slow with so much. So I ask you all, is there a big difference in speed/processing between a standard BlackBook and a "maximized" one? Thanks!
