Retail sales on tablets are growing considerably faster than those on smartphones in the UK, even though smartphone usage is far more common than tablet usage. Tablets—with their larger, more inviting screens and their general use at home in the evenings, typically via broadband connection—will contribute roughly double the level of sales than smartphones will this year, accounting for nearly two-thirds of total UK mcommerce sales. Most nontablet-based mcommerce sales in the UK occur on smartphones. eMarketer expects tablet-based retail mcommerce sales to more than double from £9.28 billion ($14.50 billion) this year to £20.96 billion ($32.75 billion) by 2018.
