Sony's portable cassette players Walkman models (bottom) and portable MiniDisc players which were produced in 1980's and 1990's are displayed at Sony's history museum in Tokyo February 23, 2012. The biggest challenge facing Sony's incoming chief executive Kazuo Hirai will be how to bridge a divide in his consumer electronics company between the 'fundamentalists", engineers who want to return the company to its orginal ethos of making cool gadgets, and "new-agers" who see the future in content and connectivity.
