<p>I am considering the Apple line of computers through cav programs. They offer the 13' macbook air, 13' macbook pro, 15' macbook pro, and 15' pro with retina display. I am thinking of going with the 13' air, the lightest one by far and recently upgraded by Apple with an intel ivy bridge processor. I plan on majoring in math and/or physics. Will this computer be sufficient? Thanks.</p>
