The Surface Pro has been quietly defining what the tablet of tomorrow will look like and what it can do. Expect the Surface Pro 4 to be lighter than its predecessor, boast a better battery life and, thanks to the latest generation Intel processor, be even faster. There's also a very strong possibility that the device will be available in a choice of screen sizes -- 11-inch and 14-inch and that on-board storage could be increased to as much as 1TB.
Microsoft could have even more in store, including updates on its Xbox game console or on its HoloLens augmented-reality system, a headset that offers computer-generated images layered on top of your view of the real world.
The official unveiling is scheduled to kick off at 11am ET in New York on October 6.
