Lenovo ThinkPad T-Series T530 15.6-inch, $779

This higher-end Lenovo uses an Intel Core i7 processor and can be packed with up to 32GB of RAM, a 1TB drive (or a 180GB solid state drive), and a 15-hour nine-cell battery. The 5.39-pound weight is a bit heftier than an ultrabook, but the T530 does measure only 1.25 inches.
