Since digital textbooks are still in their infancy, it might be tough to determine success in that market just yet. But so far, it appears Apple is doing quite well.
The iPhone maker reportedly sold 350,000 digital textbooks through its iBookstore in just its first three days of availability, Global Equities Research has revealed, according to All Things Digital, which obtained the data from the analyst firm. Global Equities Research monitors textbook downloads through its own "proprietary tracking system," All Things Digital said today. The firm doesn't disclose how that system works.
