Kishimoto said something about never bringing guns into Naruto.. because you can't dodge them or something-something lol
Naruto has computers (kabuto was on one when talking to Kimimaru), TV's (There's one in Sasuke's room) camara's, blah blah... I think the thing that kinda threw me off was watching the movie, where there were trains and movie theaters.. o_O
Well I guess I shouldn't be surprised about the movie theaters part.. since Ichi Ichi Romance became a movie long ago.. ^_^;
Anyway... I think life is pretty "advanced" outside the hidden villages, but in the hidden villages is kinda primitive
