The Windows 8 platform is a “large reason” why consumers are hesitant to buy 2-in-1 tablets, according to a report out Tuesday by the International Data Corporation.

The report also stated that worldwide sales of tablets will take a tumble in the next four years. The year-over-year growth will go down from 52.5% in 2013 to just 7.2% in 2018. The market share stall includes tablets such as the iPad, which will see its first full year of sale declines in 2014.

Most 2-in-1 tablets come with Windows 8 installed on them, making consumers less interested in purchasing them. This means that Android will continue to dominate the market in 2018, beating out iOS by nearly 40%.

IDC Program Director Ryan Keith said that one of the main reasons for the decline is because consumers are holding on to their devices for longer periods of time instead of upgrading, as one would do with a smartphone.

Keith also said consumers are using their smartphones “for a variety of computing tasks,” suggesting that the smartphone industry is a direct competitor to the tablet industry.

So what’s this mean for Microsoft Surface?

It could potentially mean that Microsoft will never see a surge of Surface sales, considering Windows leads the 2-in-1 market with other less expensive devices.
