The growing maturity of the smartphone and tablet markets were readily apparent in Apple's financial results for the second quarter of its fiscal 2014, which runs from the beginning of January to the end of March. Even though it sold a few more iPhones than it did in the second quarter of 2013, it sold slightly fewer iPads, and both revenues and profit margins were up a little from last year (think single-digit percentage growth). There's no question that Apple is still making money hand over fist: it reported profits of $10.2 billion on revenue of $45.6 billion, giving it a profit margin of 39.3 percent and beating its own upper guidance of $44 billion from last quarter—those margins also beat the company's upper guidance of 38 percent.
