The 16-gigabyte version of Google\'s Nexus 7 tablet is back on the Google Play store, after a week during which it was unavailable, Google said. Google Play said it will take three to five business days to deliver the $249 16-gigabyte version that was temporarily unavailable on the site and in many retail stores in the United States, Computerworld reported Wednesday. A number of retailers had reported trouble meeting the unexpectedly high demand for the larger-capacity Nexus 7 almost from the start of sales. The 8-gigabyte version, at $199, has been available on Google Play since the Nexus tablet went on sale July 13. When the Nexus 7 was released, the tablet \"experienced a jump in [Web] usage that has not been seen outside of the iPad,\" Gabe Donnini, a data solutions engineer for Chitika Insights, said. Google\'s restock of the 16 GB version didn\'t come as a surprise, he said. \"The company was expending a lot of effort into making sure that they could meet consumer demand,\" he said. \"The shortage was never projected to be a long-term issue.\"
