Apple can look forward to a record breaking March quarter, thanks to surging iPhone sales. Between January and March 2015, the company sold 61.2 million units, an increase of 40 percent compared to the same period last year. By contrast, iPad sales continue to slump, decreasing 23 percent compared to last year. This means Apple’s tablet sales have now declined for the fifth consecutive quarter. Still, given that the company raked in $13.6 billion in profit, it should be able to handle flagging iPad sales, as long as the iPhone continues to sell well.
