yourdeadin,

I'll just copy and paste what I said earlier in this thread about livecd's for someone wanting to LEARN linux.

copy, because that won't do much for anyone, to be honest.

You can't install programs. You can't modify configuration files. You may or may not have a good hardware detection on the CD, and if you don't that can be a huge turn off. It's going to run slower than normal because it's in RAM and not RAM+Hard drive.

They won't be learning Linux. They will be learning an interface.
Seriously people, let the guy learn, not test out an INTERFACE (which is a gui, NOT linux itself) which will most likely completely change when he finally installs his own X server and decided interface. And it certainly won't help him learn a command line since Live-cd's filesystems remain unmodifiable and thus learning how to configure your system is out of the question.
