I own a Mini, which I love, and now I want a notebook. I'm learning towards the Macbook because the Pro models are too large and heavy for my taste. I own a PC laptop that is heavy and very powerful but I hate toting it around for quick trips so basically I leave it at home and use my iphone for day trips or overnighters. Doing that works most of the time but sometimes I would rather use a notebook. Anyway, my brother just got the 2.4ghz/2GB White Macbook. I helped him set it up and I liked using it. My questions are: 1) does the 2GB make a big deal versus 1GB in the lower model? 2) why does the black macbook cost more? One person at the apple store said the casing was better than the white. Is that true? I read the guide and couldn't find an explanation. 3) I like the Air of course for its weight but the cost is obviously higher. Should I just skip the macbook and save for the air?
