Heap's analysis of millions of anonymized online orders from seven major U.S. ecommerce sites reveals that, as of September 2018, desktop sales still dominate with 56% of the sales, while mobile sales account for 36% and are on the rise. Tablets, on the other hand, contribute only 9% and are declining rapidly. The study highlights the prominence of Apple platforms in ecommerce, with iOS and Mac collectively responsible for 62.6% of all sales, significantly outpacing Microsoft Windows and Google platforms. Despite the overall growth of mobile sales, desktop remains the primary platform for ecommerce transactions, although the share of sales on mobile is rapidly increasing. Meanwhile, Apple's operating systems continue to grow their share in the market, while Windows and Android see a decline, with Google’s Chrome OS showing the fastest growth rate despite its small market share.
