At some point Apple had three line of MacBooks (Pro, regular and Air). That seemed to make perfect sense. People who want light, long battery life go for Air, people who want processing power go for Pro.
The strange thing is that Apple killed processing power in favour of more Air like features. That doesn't seem to make much sense in a 15" laptop.
