Motion Computing will unveil the new M1300 Tablet PC on 12 May with Intel's Centrino package of chips.
The new Tablet PC will feature the ultra-low voltage version of the Pentium M processor running at 900MHz, said Scott Eckert, president and chief executive officer of Motion.
The M1300 will come with a 20Gbyte hard drive, 256Mbytes of memory, three USB (universal serial bus) 2.0 ports, and Intel's Pro Wireless 802.11b wireless networking chip.
The device builds on Motion's first Tablet PC product, the M1200, launched along with Microsoft's Windows XP Tablet PC Edition last November.
Motion will make a version of the M1300 available with 802.11a or 802.11g wireless capability later this year.
Pricing and battery life information will not be available before the launch. The Centrino package is more expensive than the previous Pentium III-M chip used in the M1200, so the newer Tablet PC is likely to cost more.
It will ship through Motion's reseller network and will also be available through Gateway and Dell Computer.
