Thinkpad

TIL the ThinkPad was named after literal Think notepads distributed by IBM.

From Wikipedia:

For decades, IBM had also distributed small notepads with the word "THINK" emblazoned on their cover to customers and employees. The name "ThinkPad" was suggested by IBM employee Denny Wainwright, who had one such notepad in his pocket.
