Initially the first iPad available only had Wi-Fi but then Apple released a version that had 3G with it as well. So now there are Apple iPads that either have Wi-Fi or 3G and there are Apple iPads that have both Wi-Fi and 3G combined. And of course you probably already know that there is various HDD sizes available as well such as the 16GB, 32GB and the massive 64GB iPad which is great for media junkies into their music and movies.
