I never had a “Smart”, but I do remember this commercial. The Smart was an adorable electronic toy with a computer form factor and a judgmental attitude. Smart quizzes you and if you get the answer right, he nods the affirmative, but get the answer wrong and he will shake his head. As you can see it pretty darn adorable (so is the kid — who looks familiar).
I still think there is room in the world for toys like this, even with all those apps for kids. It is hard to take replace a toy that will physically respond, even in the simplest form.
