I agree with you. If people know what they are doing then there should'nt be any problems. No offence to macandpc, but im guessing that he does'nt know what hes doing, because he has came here for advice.
Also worth mentioning that there are a few programs that are very buggy (i cant remember the names now, but i've seen a few problems on here caused by them) so in that case, it does'nt matter if you know what your doing or not, your're still gonna have problems.
All we can do is outline the risks, and then he can make an informed decision at his own risk.
