Sony Vaio X series

The Vaio X series is a line of high-end ultraportable notebook computers from Sony introduced in September 2009, claiming to be the world's lightest notebook, at 655 grams. It features an 11.1", 16:9, 1366x768 LED-lit LCD screen with built-in webcam, 2GB of DDR2 RAM, a choice of 64, 128 or 256 GB SSD, Intel Atom Z540 1.86 GHz or Z550 2.00 GHz, WWAN.
The choice of the slower Intel Atom CPU, rather than a Core 2 chip, arguably places the device in the netbook class, however its pricing at over $1000, and other hardware aspects, such as the high resolution screen, Windows 7 on all models, and SSD usage suggest that it is a full notebook.
The device features an SD and Memory Stick reader, Bluetooth support, 2 USB ports, and a VGA port. Due to its thickness, the Ethernet port is angled, as a square-on port would be taller than the laptop.
Users wanting extended battery life can use the included extended battery, which is described as a battery-stand, tilting the laptop at an angle.
