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!
