In trying to decide between the low-end white macbook and the mid-end white book, here are the differences I've found and where I stand on them: 1 Gig vs. 2 Gig: Doesn't matter in the long run because I'll update to 4 Gig from third party supplier; although having only 1 Gig will force me to upgrade sooner. 120 Gig v. 160 Gig hard disk: doesn't matter because I'll be getting a third party 320 Gig disk. Combo drive vs. super drive: Doesn't matter because I have an external DVD burner for those rare times when I need to burn DVDs. 2.1 Ghz v. 2.4 Ghz: In the short run, I doubt I'll see the difference, although in the long run the 2.4 Ghz might be a viable machine for a bit longer. So I'm thinking I'd put $200 in my pocket and get the low-end machine. Any thoughts?
