I absolutely do! Especially at conventions--not only are video games a good way for me to decompress from sensory overload, but a lot of other people bring their 3DSes as well, so it's easy to get Streetpasses or find someone to challenge to a quick Pokemon battle or what have you.
That reminds me, I really should check up on my Animal Crossing town...
