Hey guys, I will getting my macbook very very soon, but was just curious: why is it that the macbook not come with sata hard drives? If I'm not wrong, sata is the improved version of ata hard drives? Is the difference very significant? Is yes, how much? How about in quality? Came to this question as I was comparing between the dell labtop models and the macbooks. Will still definitely get the macbook nonetheless as I totally fell in love with macs when I started playing around with them today at the shop. Also, I understand that the Leopard OS X will be out in October, and was wondering if the macbooks then will be sold with Leopard installed? Thanks in advance guys!
