So if you buy AppleCare for your device you get 2 additional years right? So 3 years in total. My iPad has AppleCare until January 2013, how is that possible if it didn't come out until April 2010?
AppleCare gives you 2 years total, not 3. You probably bought your iPad in January of 2011. It doesn't count from the day you got the AppleCare warranty.
