You may have heard by now that it was a strong quarter for Apple device sales, especially iPhones and Macs. However, seasonality can sometimes mask longer-term trends, which is why I also like to look at 4-quarter rolling averages.

Using historical data from Bare Figures and current data from Apple, the graph below shows what moving averages look like for iPad, iPhone and Mac unit sales. Note that quarters are labeled as calendar-year quarters, not Apple fiscal-year quarters.

Even discounting seasonality, you can see how iPhone sales have soared. iPad sales continue to decline versus the tablet's glory years.

Click (or tap on mobile) on device names in the legend to turn them on and off. You'll need to do so -- turn off iPad and iPhone data, that is -- in order to see the trend for Macs, since unit sales are so much lower. You'll then see that Mac sales have been on an upward trend since a (normalized) dip in 2013, and they had their highest sales ever -- with averaging as well as without.

Mouse over (or tap on mobile) points to see underlying data.

Why is Apple letting Macs rot on the tree?
