BIOS Magazine posted a review on the Sony VAIO VGN-TX3XP

If you're after the ultimate ultra-portable laptop PC, you may not
need to look any further than Sony's astonishing VAIO TX-Series (from 1498
ex. VAT) - it redefines the meaning of world class in mobile computing. Built
from carbon fibre that's twice as strong, a third lighter and four times
more rigid than normal plastics, it contains some of the most advanced
technology ever to feature in the VAIO range.
