All this has happened before and all this will happen again. The latest numbers from Canalys show that Android has now overtaken iOS as the world’s most-used tablet operating system, thanks largely to a flood of smaller devices put on the market by Samsung. Overall Canalys found that Samsung’s tablet shipments nearly quadrupled between the second quarter of 2012 and the second quarter of 2013, going from just 1.9 million last year to 7.4 million this year. Samsung wasn’t the only manufacturer to show a big increase in tablet shipments, however, as Amazon’s shipments grew from 425,000 in Q2 2012 to 1.55 million in Q2 2013 while Lenovo’s tablet shipments grew from 354,000 in Q2 2012 to 1.5 million in Q2 2013. Canalys also says that Apple’s tablet shipments have actually declined year-over-year, going from more than 17 million in the second quarter last year to 14.6 million in the second quarter this year.
