The LG 13.3″ Xnote Z330 Ultrabook is the thinnest i7 laptop out there and the 14″ Z430 is a close second.
The Z330 measures in at 315.4mm (12.41 inches) x 214.7mm (8.452 inches) x 14.7mm (.5787 inches)and 1.21kg(2.7 lbs), while the Z440 is a little larger at 329.4mm(12.9685 inches) x 226(8.8976 inches) x 19.9 mm(.7834 inches) and 1.5kg (3.3 lbs).
The LG Z330 has a 13.3-inch 1366 x 768 LED-backit display, a choice of Intel Core i3, i5 or i7 processors, 4GB of DDR3 memory and HD 3000 graphics, along with either a 120GB or 256GB SSD, 10/100 ethernet, WiFi b/g/n and Bluetooth 3.0+HS.
The LG Z430 has a larger display at 14 inches, though it has the same resolution as the Z330. The Z430 increases the maximum supported RAM to 8GB. Storage is different also, with a standard 500GB HDD paired with an optional 16GB or 128GB of SSD storage.
No word yet on pricing. These look awesome considering I am using a Netbook right now with an Atom processor as a secondary computer. With CES coming upon us this month their will probably be something smaller yet.
