Sprint must be sitting on a slow moving pile of ZTE Optik tablets, because they are about to kick off a deal that will see the device delivered free of charge to any customer purchasing a new smartphone. Details of the deal recently leaked, pinning the fire sale to August 12th. The ZTE Optik is by no means a bad tablet, but it isn’t a great one either. Given the recent launch of the Nexus 7 and other aggressive maneuvers in the 7-inch display market (including rumors of an iPad Mini), the Optik doesn’t stand much of chance. If Sprint can get rid of a few while coaxing customers into buying some smartphones, they will do better than they might otherwise. The deal ends September 30th.
