Sharp has taken the wraps off a notebook computer it claims is the thinnest and lightest 12.1in screen notebook computer ever produced.

Blessed with the unwieldy name of PC-MT1-H1, the machine is 16.6mm deep at its thinnest point and weighs 1.3kg, says Sharp.

The new computer will go on sale in Japan for around £1,180. Sharp also plans to sell the machine elsewhere, although a spokeswoman said precise launch plans have not yet been decided.

The portable PC’s vital stats compare well with other 12.1in screen models’. Sony's Vaio R505 is 23mm thick and weighs 1.7kg, IBM's ThinkPad i-1620 is 30mm thick and weighs 1.6kg and NEC's Lavie M-series machines are 29mm thick and weigh 1.6kg.

Sharp's latest notebook is based around Intel's Mobile Pentium III 500 processor running and includes 128MB of memory, a 20GB hard disk, Fast Ethernet port, a single slot each for PC Card and CompactFlash cards and two USB ports.

Floppy and CD-ROM drives are supplied as external units. Sharp says its latest notebook will operate for 3.3 hours using the standard power pack, with up to 10 hours available on a long-life battery.
