Google and NVIDIA together faced their second setback together in as many months today as a leak on Saturday revealed that Staples was pulling the ViewSonic gTablet from shelves. The Android 2.2 tablet is being shipped away due to a "manufacturing defect" and its display area removed entirely. No indication has been given to the CrunchGear tipster that the gTablet will ever return, and customers seeing this week's flyer will be told that there's no equivalent replacement because of how soon it was brought to market.
