As I just found out by d/l'ing Mandrake 9.1, Knoppix, Redhat9, and Alt Linux Junior, LINUX has sure changed. I am no expert, but I am also not a "gnubee".
I had a 486 and was amazed at how much faster Linux was than Win95. Linux, mostly RH and MDK have been fine whenever I used it.
That said, I have downloaded all of the above to "play with" on an old P200MMX. My gosh...what did they do to linix????
They are as slow as Win XP, but usable.
My thoughts....I believe I will go back to Mandrake 9.1...if any...although I may try  Debian.
Redhat9...Mostly GNOME support...very few packages for KDE.
Mandrake9.1...rather complete but puts too much on system...in case. Does not have stuff like XNC, Linneighborhood, etc on 3CD distro. KDS Control panel is great and config tools seem to be better for me than RedHat.
Knoppix is great as it does not use hdd. You can boot it from cd (or floppy) and play all you want...go to sites with junque on them and know when you shut down, nothing is left on your machine.
I tried Alt Linux last night, but is mostly MDK anyway, so I may as well stay with that.
Anyway, I replied as I just am now going thru the same decision as you!

Depends on the system ... if you are installing it on an old old PC like a 486 or Pentium ... you are gonna need to go with an old distro, or any version of like .. slack or probably Debian .....
If you have a nice system .. and you are lazy .. and want all the eyecandy of KDE3.1 ... then I recommend Mandrake 9.1[/quote]
