LaptopBroker: "Lenovo ThinkPad X61 is an ultraportable laptop. The X61 is a condensed version of X60 albeit only in its physical size and weight. There are no compromises on quality, speed, or features. Lenovo ThinkPad X61 has been able to clamp on small shortcomings of X60 model so that X61 is an impeccable successor.
