Personal computers for as little as ¥1 are currently on sale, attracting flocks of customers and sending shock waves through Japanese PC makers.

Major electronics retailers Bic Camera Inc. and Yodobashi Camera Co. have since July been selling a package of a netbook computer and an Internet connection card for as cheap as ¥100, or sometimes even ¥1, on condition that customers keep using EMobile Ltd.'s wireless data service for at least two years.

A netbook is a simplified notebook computer with a smaller display and no DVD drive. It is used mainly to surf the Internet and for e-mail.
