I am going to order a MBA 11" this week. I could really use some advice on what specifications I should buy. I will be using the laptop for your everyday basic needs (music, pictures, occasional movie, surfing the web, e-mails, word processing etc.) I am definitely going to upgrade the ram to 4gb because I think it is worth the $100 and you can't upgrade later. So, basically I don't know if I should buy the base model with 4gb ram, or if I should buy the 128gb model with 4gb ram. Then if I decide to go with the 128gb model, then you get the opportunity to get the faster processor. Does anyone have any experience with the 2 different processor speeds? Is there a significant difference between the 1.4ghz and 1.6ghz? Thanks in advance for your help!
