The Sony Vaio VGN-NW270F/S is a low-cost, Blu-ray-equipped laptop that makes a great choice for home use and, should you be willing to tote around a 15-inch machine, a decent choice as your everyday, take-it-with-you laptop.
The Toshiba Satellite U505-S2870 is rather tank-like for a 13.3-inch thin-and-light. We'd be more willing to tote it around if its heavy-armor feel extended to the flimsy keyboard.
