If you think about it, it makes sense to take this route, rather than the PS Vita one. The screen is bigger, the PlayStation 3 controller is more comfortable to hold and easier to operate than the Vita. Furthermore, think about the savings in games. A regular PS Vita game costs significantly more than those in the Play Store.
Granted, the Vita is way cheaper to buy than the Galaxy Note, but the expensive storage and games, or the lack there of, make the this seem like a viable alternative.
