Microsoft's large Surface Hub for businesses will begin shipping on January 1, 2016 instead of September 1, 2015. The conferencing system's preorders began in July, but the device's release date has been pushed back. Microsoft is releasing two models, a 55-inch Intel Core i5 Surface Hub and an 84-inch Intel Core i7 Surface Hub.

The smaller device will go for $6,999 and the larger Surface Hub will cost $19,999.

A custom version of Windows 10 is found on the Surface Hub, as are custom versions of OneNote, Skype for Business, and Office.

Preorders are still being accepted for the Surface Hub.
