Key things to know about Microsoft's Surface Hub Tablet

Software giant Microsoft on Wednesday revealed the price of its massive 84-inch Surface Hub Tablet, which the company hopes will become a fixture in meeting rooms around the world.

The wall mounted video-conferencing and digital whiteboard device will be available for $20,000, making it the most expensive product in its hardware line-up.

It will run a custom version of Windows 10, Microsoft's new operating system due out in late July. Deliveries will start in September. A smaller 55-inch version of the tablet will sell for $7,000.

Despite the hefty price tag, Microsoft is betting that the Surface Hub will appeal to businesses that are used to spending multiples of that amount on conference room facilities.

The larger Surface Hub model, which is just over 4 inches (10 cm) thick and weighs 280 lbs (127 kg), features the biggest single piece of glass for an electronic product in production, said Mike Angiulo, who runs Microsoft's devices group.

It is the latest step in Microsoft's foray into high-tech hardware, starting with the launch of the Surface tablet in 2012 and the purchase of Nokia's handset business last year.
