Okay so I think I am going to buy an 11 inch MBA base model 64 gig SSD 4 gigs of ram etc. Yes I'm going with the cheapest possible set up because I want a mac notebook. It seems like a good fit for me. Youtube, facebook, web surfing, word processing. very simple stuff. My Question How difficult is it to set up some sort of network where I can use my Desktop's, a PowerMac G5, HDD space and optical drive.
