Juniper Research predicted that today's dominant tablet vendors are in for a rough ride in the coming years, as more agile players develop low-cost models and an array of new form factors, appealing to a wider consumer base than current offerings. As a result, the research company expects the combined market share of the two dominant companies, Apple and Samsung, to fall to 38 per cent by 2019 in what the company describes as a "tectonic shift" in the market. For example, Juniper expects smaller player Lenovo to ship an additional 30 million units per annum by 2019, fuelled by sales of its Yoga range worldwide, as well as a varied line-up of devices in its home market.
