Apple chief financial officer Peter Oppenheimer has said that $1.7bn of Apple's $9.6bn in revenue was generated through sales at Apple's network of retail stores. It was "a year for the record books," according to Oppenheimer.

Apple exited the quarter with 204 stores in operation, including its third store in Manhattan, where it devotes one entire floor to Genius Bar operations, personal training and pro labs.

With an average of 201 stores open during the quarter, Apple saw each store generate $8.5m in average revenue from each store, compared to $6.6m for the same quarter a year ago. Apple also saw 64 per cent year-over-year growth in Mac sales at the retail stores.

Apple's retail stores have always attracted non-Mac users, and that hasn't changed. Apple indicated that more than 50 per cent of customers buying Macs at retail stores were new to the platform. Apple counts 14,700 visitors per store per week.

Apple recently started a new concierge service that enables Apple Store customers to set up a personal shopping experience with a Mac specialist. Oppenheimer said that those teams were very well received by customers, and Apple Stores hosted more than 300,000 personal training sessions during the quarter - a new all-time high.

Apple also ended the quarter with placements in 286 Best Buy big-box retail stores. Apple COO Tim cook said that this has "added to the Mac momentum" throughout North America. What's more, Apple and Best Buy will expand their partnership further. Apple has agreed with Best Buy to move to about 600 retail stores over the next six months.

Apple plans to open 35 to 40 new stores in the 2008 financial year. About two dozen Apple Stores are now operating outside the United States, according to Oppenheimer, and more stores will open internationally in 2008 than in 2007, including the company's first store in China.
