At the end of 2018, laptops overtook tablets & notebooks as most popular computing device.  Desktop & tower units continue to decline in use

The best year the computer market had in the last 9 years was 2014, when sales were well above half a billion dollars worldwide—and 230.1 million of those sales were of tablets such as the Apple iPad. The whole market has been shrinking since then; for the most part, everyone who needs a computer has one. But that goes double for tablets.

Since that high, sales have gone down to 150.3 million units last year (a 35 percent drop since 2014). Projections indicate the number dropping to 134.1 million tablets to ship in 2022. That’s still better than how desktops are doing. They have been on the decline even longer, going back to 2010’s sale of 157 million units worldwide; sales have dropped 40 percent since then. The forecast for 2022 is that only 84.5 million desktops will sell.
