Spyder32, it all depends on what rajunpl means by unix. If he is talking about one of the unix like systems(freebsd, openbsd, netbsd), then no it does not have to be all command line. He should learn the command line whether he is using linux or one of the bsd's to get the most out of his system.
If he is talking about Unix, then he will have to pay for its use and learn the command line.
