IBM announced the ThinkPad X series (starting with the X20) in September 2000, to give “workers on the move a better experience in extra-thin and extra-light mobile computing.” The first X series laptops were described as slimmer than a deck of cards and lighter than a half-gallon of milk, despite a 12.1-inch TFT screen. The X series replaced both the 240 and 570 series, and the line continued under Lenovo after 2005.
This is a group of X series ThinkPads from the collection, lined up together.
