ThinkPad has maintained continuous production since October 1992, surviving the IBM-to-Lenovo transition that skeptics feared would break the brand. The laptop line spans over three decades with remarkable visual consistency, from the original 700C to today's P14s Gen 6 machines. This represents one of computing's longest-running commercial laptop families.

IBM's original 700C launched with a 10.4-inch active-matrix color TFT display priced around US$4,350, featuring the iconic TrackPoint and matte-black design that became ThinkPad signatures. The MoMA-accessioned 701c butterfly keyboard (1995) and titanium-clad T20 (2000) marked key evolutionary points. When Lenovo acquired ThinkPad in 2005, engineering and design carried over largely intact.

Lenovo reached 60 million ThinkPad units sold by 2010, proving the brand's resilience. Today's P14s Gen 6 AMD models pack 96 GB DDR5 memory and Copilot+ NPUs, capable of running 70-billion-parameter LLMs locally on business chassis. The design language remains recognizably consistent across 34 years.

Design integrity stems from Richard Sapper's original vision: black aesthetics that age well and function across interiors. Key elements like the TrackPoint, 7-row keyboard, and enterprise security stack survived corporate ownership changes. Modern ThinkPads still serve developers who need reliable tools for AI workloads, maintaining the original formula while adapting to contemporary demands.
