its for those who are on the go and dont have a netbook or laptop
or when they dont want to bring their machines
im sure that the 3ds battery will last longer then my laptops
also, 3ds is mor conveniant for travel it think
waiting in an airport, get connected to wifi, and logon + play minecraft, and when done, close
or pull out big laptop, turn it on and wait 2 min, connect adding another minute, open minecraft and login
and when ur done, wait 3 min for it to shut down
i think 3ds would be better for travel and minecraft is an addicting game that makes time fly
esspecially when u throw you watch off a tower
