Apple's retail outlets are outselling PC-focused stores by as much as ten to one, according to a report from investment research firm Bernstein Research.
The study found that the average Apple store sold around 21.4 Macs daily, while a PC retailer sold, on average, less than two per day.
The report also found that Apple's retail presence had increased by 26 per cent during 2007.
Speaking about the findings, senior analyst Toni Sacconaghi said: "We estimate that the stores, which collectively represent just 2.5 per cent of the Mac’s global distribution points, drove more than one third of its market share gain during the year."
He warned, however, that Apple was struggling to make significant profits in the face of the increasing costs of maintaining its designer customer experience.
