Apple MacBook Pro 13-inch (Retina Display). It's not leather, but shouldn't it be? My current computer got me through my undergraduate work, but I don't think it's got the gusto to get me through my graduate work. If, and only if, you have a spare MacBook lying around, perhaps you could show me how well it fits in the bag!
Most of us can agree that Apple makes outstanding commercials and their customers are very loyal. I love apple products for their sleek designs and long lifespan. It would be a dream to work with them.
