Apple has signed a lease for a fourth retail store in Colorado. The company has leased 4,900 square feet in the Twenty Ninth Street area of Boulder, Colorado, in the midst of a huge redevelopment project, according to the DailyCamera. The store is set to open in the fall, according to the report, wich also stated that Boulder has an above-average Mac user base in Boulder due to the University of Colorado and its students. One local filmmaker told the DailyCamera that many Boulder residents already travel to the Cherry Creek Apple store because "employees there are better trained and computer-savvy than those at other computer stores."
