Goal-line technology is the only new device we require in football. It is the simplest debate- was it in or wasn't it? And therefore, it is the easiest to answer. Using tv footage to debate wether or not it was offisde/foul/penalty is done every weekend on MotD and doesn't prove anything anyway. As for keeping football the same at every level- we only get a referee when we play amateur and he's got to judge offsides as well.
