No, nobody says 'Knoppix sucks'. Knoppix is optimised for use as Live Linux and if you install it on hdd there are problems. Yes - there are other Live Linux's, almost WYSYWYG - you try it and if you like it, after instalation on hdd it is almost 100% as it was in Live mode. Knoppix is not made this way, that's all.

@newuser111:"whats really the downside to using knoppix on a hard drive install? everything works fine as far as i can tell" - This is true until you install some aplication or change something other way, than problems begin.
