Apple has further knocked back the cost of refurbished iPads at its online store. The iPad 2 is now available for as little as $319 in the case of a 16GB Wi-Fi model, a $30 price drop. Other models have had their prices reduced by up to $50, such as the 64GB 3G tablet, which is just $629. The only other exception in fact is the 16GB 3G, which has been slashed by $30 to $449.
