The ASUS U31JG packs an Intel Core i3 processor, Nvidia graphics with Optimus technology and almost eight hours of battery life into a thin and light 13.3-inch chassis weighing less than four pounds. What's not to like? Read our review.
Our ASUS U31JG-A1 review unit has the following specifications:
Unlike its 14-inch brother, the U41JF, the U31JG lacks an internal optical drive. Otherwise the specifications are decent for its size and weight. The Intel Core i3 processor/4GB RAM/500GB hard drive are more than ample for everyday tasks, though it won't win any performance contests. The MSRP is on the high side; as configured it would present a better value priced $100-150 less.
Build and Design

The U31JG has a moderately attractive two-tone exterior. The silver trim wrapping around the chassis is a nice touch. ASUS made the unfortunate decision to use glossy plastic for the keyboard and screen surrounds; it looks good only in pictures. In real life, it smudges up too fast and is a chore to keep clean.
The U31JG's chassis is made of plastic. Overall build quality is about average for a consumer notebook; the chassis exhibits moderate flex when twisted by the corners. The palm rest and keyboard surround area tend to cave inwards when pressed down upon, though not alarmingly so. The palm rest is not actually made of aluminum; alas it is only lookalike plastic.

One positive aspect of the U31JG's design is the relative lack of LED lights; using this machine in the dark is not distracting. Although that's a nice feature, I wish ASUS had included dedicated volume control buttons.

Ports and Features
The port selection on the U31JG is quite basic, the only notable inclusion being HDMI for connection to HDTVs and projectors. It lacks ExpressCard, USB 3.0, DisplayPort, and eSATA. All picture descriptions are left to right.
