Dell has unveiled two lighter notebooks, the Inspiron 300m and Latitude X300.
Both machines weigh less than 1.35kg and have become the lightest notebooks in Dell's inventory.
Each PC uses Intel's Centrino package of chips, comprising the low-voltage Pentium M processor, a mobile chipset and the Intel Pro/Wireless 2100 chip for accessing 802.11b wireless networks.
The Latitude X300 comes in a base configuration with a 1.2GHz Low Voltage Pentium M processor, 128Mbytes of DDR (double data rate) SDRAM (synchronous dynamic RAM), a 20Gbyte hard drive, a CD-Rom drive, and a 12.1in display for $1,599 (£956).
A base configuration of the Inspiron 300m also costs $1,599 with the 1.2GHz Low Voltage Pentium M chip, 256Mbytes of DDR SDRAM, a 30Gbyte hard drive, a DVD-Rom/CD-RW drive, and a 12.1in display.
The Inspiron 300m will be available for purchase from Dell's website.
