Company CEO Steve Ballmer says that Surface tablet sales have been modest, partially because it’s available through only the Microsoft Store online and a handful of brick-and-mortar retailers in the U.S. The entry level model of the tablet initially sold out online.

As for stock shortages, Ballmer said, “It’s a good sign. [Microsoft will] fix this problem quickly”.

Ballmer also revealed that the high-definition model of Surface, which features a 3rd Gen Intel Ivy Bridge Core i5 Processor with Intel HD Graphics 4000, 4GB of memory, and solid-state drives up to 128GB, will be released in the new year.
