Qualcomm unveiled new mobile chipset on Nov-14. While nothing have been said about UMPCs, the specs seem an overkill for a smartphone or communicators. See, the specs
"... supports HSPA data rates of up to 7.2 Mbps on the downlink and 5.76 on the uplink, with full backward compatibility. The dual-mode QSD8650 supports HSPA, as well as CDMA2000® 1xEV-DO Rev. B, with full backward compatibility. The two solutions feature a custom gigahertz microprocessor core paired with Qualcomm's sixth-generation DSP core running at 600 MHz for unsurpassed mobile performance delivering an instant-on and always-connected user experience. Snapdragon's support for HD video decode, 12 megapixel camera, GPS, broadcast TV (using MediaFLO, DVBH-H and/or ISDB-T), Wi-Fi and Bluetooth deliver even greater opportunities for device manufacturers to design compelling mobile products that make the promise of constant, seamless connectivity in an extremely thin and small form-factor a reality. "
This setup should be able to run not only Windows Mobile but also some serios Linux or XP setup, as was indirectly confirmed by this quote "The Company will be demonstrating the Snapdragon platform running both Windows Mobile and Linux to deliver productivity applications, entertainment applications and advanced user experiences at Qualcomm's New York Analyst Meeting. "
Hope we will see new UMPCs from their launch partner HTC sooner than later.
