Think about this.
The first cell phone was developed in 1947 http://en.wikipedia.org/wiki/History_of_mobile_phones
The Internet starts in 1950 http://en.wikipedia.org/wiki/History_of_the_Internet
Tablet computers were prototyped in 1968 http://en.wikipedia.org/wiki/Dynabook
It's the economic improvement since that created the iPad. iPad is not in anyway comparable to the technological innovation in 1960 that put a man to the moon.
It's like someone using VS2010 and C# 4.0 seeing the SICP book for the first time, or a chance encounter with LISP. And you would know we didn't improve that much since the days we put a man on the moon.
