A new report has revealed that shipments of hybrid devices are on track for sharp growth in 2015, driven by hybrid ultramobiles.
Hybrid devices are on track to reach 21.5 million units shipped globally in 2015, a rise of 70% from 2014.
Hybrid devices are anticipated to make up 12% of mobile PC sales this year, and then continue to increase to 26% by 2019, Gartner said in its report.
Gartner research director Tracy Tsai said: "Of the 21.5 million hybrid devices shipped in 2015, 8 million will be ultramobile tablets (two-in-one tablets) and 13.5 million hybrid ultramobiles (two-in-one detachable and convertible ultramobiles).
"This will make hybrid ultramobiles the fastest-growing segment of the mobile PC market with 77 percent year-on-year growth."
Hybrid ultramobiles are yet to make an impact in the enterprise segment, but Tsai said it is likely to change with the introduction of Windows 10.
Tsai said: "Windows 10 on hybrid ultramobiles will offer a better user experience with touch and voice as well as universal Windows apps – apps written just once that receive device-specific user experience tweaks to allow them to run on different Windows devices."
Asus led the hybrid ultramobile category in 2014 with 41% market share. The company shipped 3.1 million hybrid ultramobile units in 2014, an increase of 263% year on year.
Lenovo was at second place with 1.9 million shipments in 2014, followed by HP with 800,000 shipments.
Gartner analysts said, despite hybrid devices achieving strong growth, clamshells will remain the mainstream form factor, accounting for 87% of mobile PCs in 2015 and 74% in 2019.
