i have a 3Ds and played AC: NL and Smash mostly. I can't play if I'm on the bus due to motion sickness and even looking at my phone reading or playing any mobile game for a longer time makes me dizzy.
i'm with Curl loves to play handheld at home. but handhelds are great due to portability and you can bring it with you anywhere. like the other poster(s) have mentioned bring it with you, play in the hotel, etc...
the hardware specs would surely be lower than home console, but 3Ds is not also on par with Vita in terms of screen resolution. my 3Ds is now with my daughter and she loves to play Smash there. She loves MK8 on the Wii U and got the MK7 as my Nintendo Reward game, hopefully she'll love playing MK on the 3Ds like she loves playing it on the Wii U.
