Growth in the global market for tablet devices is likely to slow significantly this year, according to the International Data Corporation.

The IDC’s latest Quarterly Tablet Tracker forecasts the market for tablets to grow by 19.4% this year, compared to growth of 51.6% in 2013.

The figure for growth this year is 3.6% lower than had been previously forecast, as the number of people who have not yet bought a tablet continues to decline.

In addition to this few of those that already own tablets seem compelled to upgrade to a new device in the near future, IDC notes.

As well as slowing demand for tablets the tracker also shows that, after years of price drops, the average selling price of devices would begin to level off this year.

The average price of a tablet fell 18.3% in 2012, IDC says, and fell a further 14.6% last year. However in 2014 the average price was likely fall by just 3.6%, the firm said.

IDC says this is partially due to an increase in high-end products, as well as a broad consumer shift away from extremely cheap devices.

Meanwhile, IDC predicts strong growth in commercial purchases of tablets – particularly in areas outside of education.

This growth could help Microsoft’s attempts to gain a bigger share of the tablet market, it says, as businesses would likely be attracted to two-in-one devices that work as a laptop or tablet – something Windows 8 is specifically designed to cater for.
