This laptop has the ExpressGate instant-on operating system that is Linux-based, which lets you boot into a basic operating system in about 10 seconds by pressing a button above the keyboard. Here you can do basic tasks, like surf the Internet using Google Chrome, view pictures, watch videos and play some basic games. Battery life with the included 8-cell battery is an astounding 9-10 hours, which is almost double what other similar laptops provide.

The term "thin and light" has a flexible meaning in the laptop world. Currently, to be truly thin, a PC must be in the same range as the MacBook Air. The Asus U31SD-A1 is a compact 13-inch laptop that should appeal to back-to-school shoppers, especially with its impressive graphics/battery life combination, despite some cut corners.

Not every laptop gets to be a star, but that doesn’t mean it’s not worth your time. A good sub-$800 thin-and-light with long battery life and good performance is nothing to sneeze at, and here, Asus delivers. Asus delivers respectable performance, long battery life, and a low price, but we wish the case were built with better materials.

The caveat with the Acer is that you have to give up about 2.5 hours of unplugged time. If you want all-day endurance along with the ability to game between classes or meetings, the U31SD-A1 is a fine choice.

The ASUS U31SD-A1 is an attractive 13-inch laptop with decent overall performance, good graphics power, and superb battery life. Overall, we prefer the Acer Aspire Timeline 3830TG, which offers even more graphics oomph and a faster Core i5 processor for the same price. The caveat with the Acer is that you have to give up about 2.5 hours of unplugged time. If you want all-day endurance along with the ability to game between classes or meetings, the U31SD-A1 is a fine choice.

The U31SD is lackluster at best in nearly every other area, however. The keyboard and touchpad are uninspiring; the build quality is questionable at best; and furthermore, there is a barebones selection of input/output ports. The ASUS U31SD is still recommendable in the end; it is a good traveling companion -- just be careful not to treat it roughly given the build quality.

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.
Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.
