Sony unveiled the ultra slim portable lines the "X-series" Vaio X netbook — a Intel Atom-powered Vaio X is built of carbon fiber and aluminum, and is only about half an inch thin and weighs only one and a half pounds. If these measurements prove to be accurate when Sony officially releases specs in October, it’ll be the thinnest, lightest PC on the market. Here's how the Vaio X series stacks up against its competitors in the form factor:

Asus Eee Seashell: 1.01"
MSI X-series: .79"
Macbook Air: .76"
Lenovo X-series: .75"
HP Voodoo Envy 133: .70"
Dell Adamo: .65"
Sony Vaio X: .5" (unofficial)
