If you want a Type Cover (better keyboard), you can buy it separately for $129.99.
The Surface has a 16:9 display, 10.6-inch screen, the edges are beveled at 22 degrees, and is just 9.3mm thick. The display has Gorilla Glass 2 and you can connect to "the strongest Wi-Fi connection ever." The case is built of magnesium, and the "liquid metal is formed into an ultra rigid and light frame" while weighing just 1.5 lbs.
Under the hood is 2GB RAM, a quad-core Tegra 3 processor, dual-cameras, Bluetooth 4.0, Stereo speakers, a full-size USB 2.0, a microSDXC card reader, Headphone jack and HD video out port.
Additionally, the device has access to all Windows apps for music, movies and more, and all games from the Windows Store. Full Microsoft Office is installed, as well.
