I'm just getting serious about researching iPad and just joined the Forum. I thought the iPad 3 was the latest and gratest. I knew about the iPad mini but didn't know they actually changed the iPad. When I look at the Apple store it just shows iPad with Retina Display. Is that any different than the iPad 3? I thought the 3 had Retina Display? I've been looking at the refurbished iPads at Apple and they have an iPad 3 for $379. I'm assuming then that's basically going to be an outdated version? I thought that was going to be the latest/gratest but just refurbished. What are the main differnces in iPad 3 vs iPad 4?
