Q: I will use it for school, carriying it arround. Use MS office on it
A: Get the Macbook. Don't get the Macbook Air. The Macbook Air was made for business people who want to enjoy a Mac while traveling, while not being bothered by wires and CDs. This is why it is so lightweight and thin. Its easier to carry around. A Macbook Air doesn't make much sense for you and it would become more of a headache to use on a regular basis. Now if you were a sales person who traveled for 250 days a year, then get the Macbook Air. It's easier to have your carry on back, open up in your lap on a plane, etc. The Macbook will contain everything you need for school and home.
