Sony VAIO Z 13-inch, $1599

This thin and light notebook belies a few impressive high-end features. The Intel Core i7 processor, available as an option, helps the Z keep pace with bigger, bulkier laptops. The system comes standard with a speed-boosting 8GB of RAM, high-end graphics, and a carbon fiber back for durability. One perk: If you watch a movie on a plane, the notebook simulates surround-sound with Dolby Home Theater.
