My friend, my video game history is long and old. Between my immediate family we have had every Nintendo and Playstation console (including PSP and VIta). Even when the PS3 was $600, I was supportive of Sony. Albeit that was a huge misstep on their part. My Wii is on a shelf currently since we have a Wii U, and I don't use it much anymore. But I've been a huge advocate of the Sony/Nintendo combo (I may also have bias from living in Japan as a kid). They are my favorite.
Also in terms of PS4 controllers, they just released this wired controller that is much better for smaller hands. My 11 year old sister might be better off playing it when she plays a PS4 game. Something you may want to consider in the future. (I do not work at Sony. I sure wish I did though).
