context_page_description: The ThinkPad X series is a line of notebook computers and convertible tablets originally produced by IBM and now marketed by Lenovo.
  IBM announced the ThinkPad X series in September 2000 with the intention of providing “workers on the move with a better experience in extra-thin and extra-light mobile computing.” The ThinkPad X series replaced both the 240 and 570 series during IBM's transition from numbered to letter series during the early 2000s. The first X Series laptops were "slimmer than a deck of cards" and "lighter than a half-gallon of milk", despite the presence of a 12.1-inch Thin-film transistor display. These design values—thin and light—continued to be integral to the ThinkPad X-series laptops' design and marketing, even after the purchase of IBM's Personal Computing Division by Lenovo. The first X Series ThinkPad released by Lenovo was the X41 in 2005.
  The ThinkPad X-series laptops from Lenovo were described by Trusted Reviews as "combining an ultraportable's weight and form factor with a durable design." The X-series laptop styles include traditional ultraportables, as well as convertible tablet designs.
