I am about to buy a MacBook. I don't know which to go with. I need help. Whichever one I get, it would be the base model. I have an iPhone 4 and an iPad 1 64gb wifi. I would use it for basic stuff like Internet and office type work. No high end graphics or anything like that. Might occasionally take it out of the house. Any likes dislikes that you guys have with either one ( one that you own and use). Also have kids. (is air fragile? Or will it be ok with kids) thanks.
