SAN FRANCISCO (04/19/2000) - Think of the quartz computing platform as a jack-of-all-trades for your handheld devices. After all, the newly unveiled Quartz design developed by Symbian Ltd. (650/598-4747, www.symbian.com) can combine a PDA and a mobile phone to offer features such as e-mail, Web browsing, telephony, and wireless connectivity with other devices. The idea behind Quartz is to make it easier for handheld devices to communicate with each other. Motorola, a partner in the Symbian consortium, plans to release a Quartz-based phone in the first half of 2001. Symbian partners Ericsson and Psion have plans for Quartz as well. No word on whether Quartz devices will also do windows.
