Of these combos, which would your or do you prefer? A.) iPad Mini 2 + MacBook Air 11" B.) iPad Air + MacBook Air 11" C.) iPad Mini 2 + MacBook Pro retina 13" D.) iPad Air + MacBook Pro retina 13" Ranked lowest to highest in cost. But the main reason for the question is to see where the overlap/redundancy is and if the premium for the display and size outweigh portability. Thanks in advance on your thoughts!
