Lenovo faced a great challenge when designing the ThinkPad X300. It had to make things really small without losing key capabilities, such as performance, battery life, quality, reliability and functionality. With thanks to Intel's ever-shrinking Centrino platform Lenovo has created a laptop that is amazingly thin and light, but still looks great, is built like a tank, and offers plenty of configuration options. As far as we're concerned the ThinkPad X300 is the best ultra-portable laptop you can currently buy.
