What is "thinkpad"

ThinkPad is a line of laptop computers and tablets by Lenovo. The series was designed, developed, and sold by IBM until Lenovo acquired the division and brand in 2005. ThinkPads are known for their minimalist, black and box design which was initially modeled in 1990 by industrial designer Richard Sapper based on the concept of a traditional Japanese Bento lunchbox revealing its nature only after being opened. According to later interviews with Sapper, he also characterized the simple ThinkPad form to be as elementary as a simple, black cigar box and with similar proportions that offers a 'surprise' when opened.

ThinkPads are popular with large businesses and schools. Older ThinkPad models are revered by technology enthusiasts, collectors and power users due to their durable design, relatively high resale value, and abundance of aftermarket replacement parts. ThinkPad laptops have been used in space and, by 2003, were the only laptops certified for use on the International Space Station.
