Sony said today that it will stop selling its Clie handheld personal digital assistants (PDA) in the United States later this year. The electronics giant said it plans to continue to develop and sell Clie PDAs in Japan. “Presently, Sony is reassessing the direction of the conventional PDA, and Sony will not introduce any new handled Clie models in the United States this fall,” Sony told CNET News.com. “Product development and sales continue for the Japanese market only. Sony is taking this time to examine the conventional PDA business and how it will transition into the future.”
