The first computer was a $6-million-dollar […]

Scientific illiteracy

A good case of illiteracy over at CNN Money: Why more people are suddenly dying on U.S. roads by Matt McFarland.

When the sale came up with the $50 tablet (Fire 7) for $35, the cost to benefit equation got a bit skewed. This is a large company branded complete tablet that is getting into the noise on the price point. Consider the $5 Rasberry Pi or the $15 Pine 64 (kickstarter) or the other $9 […]
