Note: Its called a concept for a reason, so don't get angry if it doesn't happen
Here's a video by Aatma Studio, best known for their futuristic iPhone 5 concept, has just released this iPad 3 concept video, featuring all the rumored differences between iPad 3, and iPads 1 and 2.
Sadly, considering the release date for the new iPad is March 7, I doubt they will be able to add the feature magnets, let alone the holograms. Yes I said holograms. Just watch the video.
