It was hard to believe the rumors that Microsoft is working on an 84-inch tablet at first, but when the company officially unveiled the Surface Hub, things started to make more sense. Designed almost exclusively for enterprise customers, the Surface Hub is meant to be used for advanced videoconferencing, and has actually drawn a lot of interest. Unfortunately, both the 55-inch and 84-inch versions of the device have been delayed again, with the a vague shipping date of “earlier next year” being given, and the price of both versions has been increased by $2,000 for new buyers. Customers who have already pre-ordered their Surface Hub(s) will still be able to pay the original price.
