Worldwide PC shipments (desktops, notebooks, two-in-ones and tablets) totaled 101 million units in Q1 2016, as total volumes dipped by 13% year-on-year to their lowest point since Q2 2011. Apple continued to lead the market into the first quarter of 2016 with shipments of just over 14 million units, despite falling 17%.

I suspect we’ll see a nice burst to shipped units when Apple updates the retina MacBook Pro.
