Apple posts record earnings for Q1 2013: $13.1b profit on $54.5b revenue, record 47.8m iPhones sold

Apple just announced its Q1 2013 earnings, and the company posted a record $13.1b profit on a record $54.5b in revenue. That's just over last year's record of $13.06b profit on $46.33b in revenue at this time last year, and well over the $8.2b profit on $36 billion in revenue in the last quarter.

Importantly, iPhone sales were a record 47.8m compared to 37.04m iPhones a year ago and 26.9m iPhones last quarter, and iPad sales also set a record at 22.9m sold, compared to 15.43m last year and 14m last quarter. Overall, Apple moved some 75m iOS devices last quarter. Interestingly, Mac sales during the holiday quarter were down to 4.1m from 5.2m last year, while the iPod continued its predictable slide, with the traditionally strong holiday sales coming in at 12.7m from 15.4m a year ago.

The results narrowly beat the consensus Wall Street projections, which had Apple posting a $12.8b profit on $54.8b in revenue. Apple also beat its own estimates, which were $11b in profits on $52b in revenue. Even still, that may not be enough for investors, who are hammering the stock in after-hours trading for being "light on revenue."

Here's the total breakdown of sales across product lines:
