The iPhone X is a bit of a mixed bag when it comes to Apple's earnings. The company just reported its first quarter 2018 financial results, a period that includes the busy holiday shopping season. 

On one hand, overall iPhone sales were down, with Apple recording 77.3 million units sold. That's about 1.3% below the 78.3 million iPhones that Apple sold during last year's holiday period.
