It might lack a touch screen, but the $999.99 Portege Z935-P390 provides a bridge between the old and new worlds with a thin, lightweight, high-performance system.
All three of these new ultrabooks are well made, reliable and are worthy of consideration for a place in your notebook bag.
At heart, I am a cheapskate, eager to save money on anything I buy. This time, however, my choice is the $1,300 Sony Vaio T13, the most expensive of the three. It has a great touch screen, the best configuration, excellent performance and the ability to run for nearly five hours on a charge. Of the three, it offers the best balance among size, weight and abilities.
