Calculator to ?

I remember my dad buying a Texas Instrument calculator in the early 1970s for about $175.00.  The 2012 currency equivalent is almost a $1000.00.  The calculator replaced his slide rule.  Today you can find calculators in bargain bins for under $5.00.  You can purchase a very good laptop today for the price of a calculator in the early 1970s.

My grandparents saw transportation move from the horse and cart to space travel.  It is exciting to be at the crux of fundamental changes in technology and education.  Where will we go?
