13.3 LCD screen. 3GB DDR3 (RAM). 500GB Hard Drive. 1.3MP Webcam. Wifi, Bluetooth, HDMI, 4-in-1 memory card reader. It weighs a little over 3 pounds, very very very slim design, perfect for travel and everything home related. Windows 7 operating system. I bought this in Hong Kong before it was released in the US and it has worked perfectly for me. It has been lightly used, not much time to use it.
