As I am sure I am not the only one who likes to have the latest and greatest, I was wondering if the MBA was really worth getting for those of you who have one. I currently have a MBP that I use for graduate school. I only use the MBP for school. I use my iMac at home for video, photos, music, etc. i am sure the MBA would be great for school. I am just wondering how much I will be sacrificing, if at all, if I sell my MBP to get a MBA. What do you think? Thanks.
