"The Surface Pro 3 is the third-generation Surface-series 2-in-1 detachable, designed, developed, marketed, and produced by Microsoft. It originally ran the Windows 8.1 Pro operating system (OS), but the optional upgrade to Windows 10 Pro (OS) operating system was later added. The Surface Pro 3 has a body made of magnesium alloy giving a gray matted finish to the back of the device. The charging port is magnetized and connects securely to the charger.It comes with an improved kickstand, allowing the device to be set at any angle between 22 and 150 degrees. The kickstand has a high resistance which provides firmness and prevents accidental sliding.The Surface Pro 3 features a larger 12 inches (30 cm) (screen display area 25.4 cm x 16.9 cm) display over its predecessor. The screen has a 3:2 aspect ratio which Microsoft claims allow the device to be used more comfortably in the portrait orientation. Because the touch screen digitizer and the pen digitizer are combined into a single layer, the screen is physically thinner than that of its predecessors, which improves viewing angle.Although the Surface Pro 3 has a larger screen than its predecessor, it is both thinner and lighter, weighing 100 grams (0.22 lb) less. Microsoft claims the Surface Pro 3 is capable of up to 9 hours of web browsing.The Surface Pro 3 is built on the 4th generation Intel Core processor with TPM chip for enterprise security. It includes a USB 3.0 port and a Mini DisplayPort on the right, an audio jack on the left, and a hot swap microSD slot on the back of the device. The microSD slot supports memory cards up to 200 GB.
