Ok I bought a MBA last week, this was my first mac EVER! and DAMN do I love OSX and Mac Products! The AIR is a great little machine! I planned on taking my desktop with me to college and having the air to take to class but now I'm second guessing myself and wondering if I should go back exchange the AIR for a PRO and sell the desktop? My question is, is the battery life + weight of the MBP adequate to carry all day from class to class? Pop it open, take notes/wifi etc? The reason I love the AIR is because its battery life + mobility factor but I'm wondering as a college student do I need this? I want to take my LAPTOP with me everywhere but i feel like the headroom the MBA creates is way to close for me... Talk to me please its an emergency I have only 5 days to make the trade!
