ARM based的surface RT不支持X86程序， 但是支持大部分usb设备，包括打印机，手机
，相机，XBOX360手柄等
Surface supports Xbox 360 USB controllers for gaming
• USB will recognize almost all devices, including cameras and will
charge your phone
• No NFC due to the Mag case interfering with the antenna
• 32GB device will have 20GB available for storage for apps/games; SD
card is for movies, pictures and music
• SDXC is supported; cards can be swapped on the fly
• Touch Cover has a Microsoft invented smart digitizer, can infer if
you meant to press the key or not
• TouchCover/TypeCover detect orientation relative to the Surface, so
it will disable the KB when closed or flipped back
• Why no 3G/4G mobile broadband? Microsoft looked at tablet sales data
activated.
• On the display not being super high resolution, Microsoft addresses
this through a three pronged method: ClearType for pixel smoothing, Custom
designed 10.6” high contrast wide angle screen and optically bonded the
screen with the thinnest optical stack anywhere on the market. In turn, the
reflectiveness of the Surface’s display is much lower than the iPad,
resulting in higher contrast of colors and more visible detail
• Why no USB 3.0? Microsoft chose USB 2.0 instead of 3.0 based on
capability of the ARM SoCs during their development timeframe
