For decades, IBM distributed small notepads with the word "THINK" emblazoned on a brown leatherette cover to customers and employees. The name "ThinkPad" was suggested by IBM employee Denny Wainwright, who had a "THINK" notepad in his pocket. The name was opposed by the IBM corporate naming committee as all the names for IBM computers were numeric at that time. "ThinkPad" was kept due to praise from journalists and the public.

Sometimes you just need to think don't you?
