When my parents bought me my first laptop, I fought tooth and nail to spend the extra money and get a bigger model. The 15-inch Dell Inspiron E1505 I cajoled them into purchasing was backpack-fillingly large and back-breakingly heavy, but man did it have screen space. Eventually, my computing needs changed. My laptop stopped being my TV, my game console, my desk, and my serving tray for late-night Bagel Bites. I needed a computer that was powerful but not quite so huge. So I bought a 13-inch MacBook Pro, which served me well until I dropped it one too many times and downloaded one too many torrents, at which point it clutched its chest and collapsed in my living room. This time I bought a 13-inch MacBook Air.
