Hurdles for iPad education drive

Linda Zecher, chief executive of Houghton Mifflin Harcourt, the US textbook publisher, believes digital devices such as tablet computers are an 'opportunity' for her industry. However, she tells Andrew Edgecliffe-Johnson, media editor, that there remain significant challenges before the technology is fully integrated into classrooms - and not just in developing countries, but in the US too. Houghton Mifflin Harcourt is a competitor of Pearson, which owns the FT.
