Isn't that thing similar to Knoppix? Anyway, live CDs are useful for some backup or educational purposes. If you want to show to a friend Linux on his/her own PC, then you're in luck. But then, it's better getting the OS itself. I have RedHat so far, and I can't use it yet, since the CPU for my Linux OS isn't assembled yet. I'm not gonna use big specs. Just a Pentium 2 Processor and 64MB RAM will do for now... Using Linux isn't as bad as I originally thought. In fact, I used one of those Live CDs before for the sole purpose of "cool" factor. Linux might not do well in the compatibility area, but it does good in the stability part!

That's insane. It's amazing what they can do with technology. Fit a whole operating system on a little disk. I love technology, I'm gonna work for geeksqaud or something like that.

Many live CDs are marketed as rescue CDs, which is what I think you mean by "saving computers." But Slax is not. It doesn't have the tools necessary to do rescue operations. But it does boot up as a nice workstation environment.

I have tried number of linux distros (latest was ubuntu) and everytime I go back to XP? I really like the idea of having an OS completely free but the problem with me is that I do not have that much time to study the configuration, is there anybody there that have tried the most user friendly linux distro (this is speaking from someone who is really new to linux)

Slax looked cool, but I went with DSL instead... It has firefox built in, along with quite a few other really useful programs, and there's a version of OpenOffice.org available from the distro sites...
If you're looking for something for school, the live cd is about 48 MB (not including OOo or anything extra you download) and can fit on a business card cd... It's *fairly* user friendly (it's my first distro) and has a decent selection of apps and games

Wow, I dident even knew that it was possible to have that. Im very impressed, you just need one cd to turn your pc to an other OS.
