I'm on the same boat as you and have recently purchased a MacBook Air a week ago. Its an absolute delight for a student such as myself to do assignments.

To maintain it I recently bought a cover and case to stop potential scratches and damage to the device which I think is a must! If you've spent a lot of money on a MacBook then you need some good protection!

Finally, I would definitely advise you to install this app called Alfred onto it as it definitely makes ease of use much more efficient.
