Wew, you don't get the point. I don't know why your acting like that but the real purpose here is that to enlighten the thread starter, and some discussion as well. He needs to learn from the experience of others about those two jobs - that is, to get some thoughts and save up some time to actually try both. That's why there's this forums, for guides and discussion.
C'mon, don't ruin this thread. <_<
