E-Ten Information Systems launched a pair of new smart phones that use Microsoft software and revealed it\u2019s in talks with the world\u2019s largest notebook computer maker to co-develop and market handsets.The company launched its OG500 handset at last week\u2019s Computex IT show in Taipei, a GSM mobile phone with PDA functionality,\u00a0which also includes GPS so users can tap into mapping programs to ensure they\u2019re never lost. The device runs on a Samsung Electronics S3C2440 processor that runs at 400MHz. Users can talk as long as four hours on the phone before its battery runs down, or use the PC functions for 10 to 15 hours.The handset also takes pictures with a 1.3-megapixel lens with 4x zoom, as well as movies. A built-in microphone captures sound for voice recordings and movies.The company released an upgrade to its OM600 smart phone, with a new 2.0-megapixel camera lens to replace the older version\u2019s 1.3-megapixel lens, and 256MB of memory instead of 128MB. It also supports push e-mail technology and runs Windows Mobile 5.0. The smart phone supports Wi-Fi, so users could surf the Internet and even download Skype\u2019s telephony software and use the handset for voice-over-IP phone calls.E-Ten is relatively new to developing handsets based on the Microsoft OS. The company is\u00a0better known for its PDAs and GPS devices. But the success of hometown rival High Tech Computer and its Microsoft-based smart phones has prompted other Taiwanese handset makers to enter the market fray.Its recent entry into the market is a disadvantage for E-Ten, but the handset maker is working on a development and marketing deal with Quanta Computer, the Taiwanese notebook maker, that could speed up its progress. Quanta has been a global player in the IT field for years, producing laptops on behalf of multinationals such as Dell and Hewlett-Packard. A pact between the two companies would enable E-Ten to extend its sales reach and customer list."We\u2019re in discussions with Quanta, but nothing\u2019s been finalized yet," said Sylvia Pan, an assistant manager at E-Ten.-Dan Nystedt, IDG News Service (Taipei Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
