The VersaPro series will be sold to companies, while home users will purchase the LaVie series.
With a 10.4in TFT display and measuring only 15mm thick, NEC's Tablet PC is smaller than most devices since the launch of Microsoft's Windows XP Tablet PC Edition in November.
NEC's Tablet PC is a slate device. Typical configuration of the VersaPro series will include the recently announced 933MHz Ultra Low Voltage Pentium III Processor-M from Intel, 256Mbytes of SDRAM (synchronous dynamic RAM), a 20Gbyte hard drive, and a lithium-ion battery for a price of ¥236,000 (£1,225).
It will be available in build-to-order configurations in Japan, but information about North American or European configurations was not immediately available.
Users can add 802.11b wireless capability to both the VersaPro and LaVie Tablet PCs.
