"We expect [BlackBerry 10] to be met with a lukewarm response at best and ultimately likely to fail," Faucette says. Faucette cites the unfamiliar user interface of BlackBerry 10, the lack of compatible accessories and few software applications as key reasons he believes BlackBerry 10 will struggle in the market. As SmartCompany reported yesterday, the BlackBerry platform currently claims around 4.3% of the world smartphone market with 7.7 million units shipped worldwide per quarter, down 34.7% year-on-year from 11.8 million units and 9.5% marketshare.
