I have a three year old iPad 1 64GB wifi only in mint cond with applecare still on it through Nov. I have a 64GB iPod Touch 3rd Gen which is really showing signs of age. I would like to buy an iPad with wireless cell on it. I can buy an iPad3 32G (Apple Referb) or iPad2 (new) with 64G. I use my iPod the most. Which should I buy?
