ThinkPad: From IBM's Bento Box to Lenovo's AI Workstations

IBM introduced the ThinkPad notebook lineup in 1992, and the brand has survived over three decades, a corporate ownership change to Lenovo in 2005, and cumulative sales exceeding 150 million units. The ThinkPad's distinctive design—featuring a black chassis, red TrackPoint pointer, and quality keyboard—has remained remarkably consistent and recognizable from the original 1992 model to modern AI workstations. What sets ThinkPad apart from other long-running laptop families is its visual and functional continuity, maintaining its core design formula while successfully adapting to evolving computing needs.
