Gateway revamps its thin-and-light design with the new M320 series. Gone are the boxy touch pad, the square mouse buttons, and the wasted wrist-rest space. Their absence allows for some thoughtful touches, such as a handy four-in-one card reader for flash memory cards and a rubbery wrist-rest coating that helps keep your hands in place when you're typing. Available in a number of configurations, the M320 series features Intel mobile processors, integrated Wi-Fi, and optical drives, all in a relatively small and light 5.5-pound package. We tested the highest-end configuration, the Gateway M320XL; unfortunately, short battery life undercut its otherwise decent performance.
