Some global sales figures from Gartner:

Worldwide tablet sales :

■   2010: 17.6 million 

■   2011: 59.8 million

■   2012:  124.8 million

■   2013:  216.3 million

■   2014: 216.1 million

■   2015: 233.4 million (forecast)

■   2016: 259.0 million (forecast)

There is talk of tablet sales fading and PCs having a revival but so far little evidence.
