1024 vs 1000 Memes

The eternal battle between marketing and reality. Hard drive manufacturers use 1MB = 1000KB to make their products seem bigger (931GB of actual storage when you buy a "1TB" drive), while the rest of the computing world knows 1MB = 1024KB. It's like ordering a dozen donuts and getting 10 because "our definition of dozen is more convenient for our profit margins." The bell curve shows most people understand the correct definition, but marketing departments and those who believe them occupy the tails of blissful ignorance.
