The next generation of Origami Ultra Mobile PCs (UMPCs) will boast enhanced features including longer battery life, larger screens, more powerful CPUs, TV tuners, GPS navigation and 3G connectivity.

New models are already on the drawing board, and slated for launch by the first quarter of next year, manufacturers say, following criticism of the first generation of Ultra Mobile PCs.

The UMPC platform, originally developed by Microsoft, is a handheld tablet-style wireless PC controlled with a touch screen and pointing devices. It has no keyboard, and early models have been faulted for their weight and short battery life. 

"We want to develop a UMPC with Intel's Yonah, the Core CPU, but keeping the same form factor," Stanley Chen, of UMPC maker Elitegroup Computer Systems (ECS), told vnunet.com at the Computex trade show in Taipei. 

The Intel Core CPU, previously known under the codename 'Yonah', comes in both dual-core and single-core versions. Intel announced an ultra-low-voltage version of the CPU earlier this week. 

Several companies are showing UMPCs at Computex, including ECS, Asustek and Amtek. ECS manufactures the H70, which is available in a variety of configurations. 

The top-of-the-line model has a 1GHz low-voltage Pentium M CPU, 1GB of memory, and a 60GB hard disk drive. In some regions, the PC is sold by Chinese firm Founder under the name Mininote.
