What Gabriel said! Added to that, iOS is no longer updated for the original iPad so you will find that some apps will not work. People who already had the app can still use it but anything that requires iOS 6 or later won't be available to you. To my mind, this will make your first iPad an unsatisfactory experience. The iPad 2 is still a current model and, although it is lacking features like Siri, it still runs the latest version of iOS.
