If I thought the hardware limitations would irritate younger gamers, I would've definitely mentioned it. My specific concerns with the limitations were outlined immediately after I mentioned them. Namely, the stylus has limitations when it comes to precision, but for kids who are used to using Crayons and such to make their masterpieces, I can't imagine that being a serious issue.
"Too often we enjoy the comfort of opinion without the discomfort of thought." - John F. Kennedy on reality
"What if everything you see is more than what you see--the person next to you is a warrior and the space that appears empty is a secret door to another world? What if something appears that shouldn't? You either dismiss it, or you accept that there is much more to the world than you think. Perhaps it really is a doorway, and if you choose to go inside, you'll find many unexpected things." - Shigeru Miyamoto on secret doors to another world
