Did you forget the negative impacts ? 
Anyways, other than the benefit of sharing the same pool of games it will most likely end up being a negative in the long term seeing as how systems need to be differentiated in software in order to give a selling point for one system over another. A lot of people aren't very fond of Nintendo consoles compared to their handhelds in general so this only hurts Nintendo's business in general as it only gives more incentives for people to not buy a Nintendo console.
