I currently own a early 2008 macbook pro 17 2.6ghz. I am looking into getting the new air with 1.8 and ssd. I am curious as if I should go with the 1.8 and do a 120 drive or should i do the ssd. I dont plan on gaming on it since I can do that on my pro or my macpro. It gets really difficult lugging this macbook pro around all day. My main concern is which is faster the ssd or the 120. Any help that you guys could point my way would be greatly appreciated. If I need to know more please point them out to me.
