I can't believe people are still upgrading their iPads. I bought an iPad 3 when it came out, and an iPad 4 for my wife when it came out. We don't really use them at all anymore since they are just big versions of our phones. We use our phones because they are more convenient, and when we need to do stuff our phone can't do, we use a computer because an iPad can't do it either.
I keep watching them come out with new iPads hoping they'll release something that will compete with a Surface, but so far, it's just a big iPod.
