I have to admit, out of all (not many, really) distros I’ve tried, I like Knoppix the best.
Wish there was an easy way to install it, or at least another distro that was comparable.
(and nobody need mention Ubuntu. If an OS can’t even run a mouse, I don’t want to fight it!).
Recently had a good experience with Gutsy Gibbon (v. 7.10 -- unlike the 7.05 Fierce Fawn, below): it automatically detected both a ZyAIR G-220 USB-based 802.11g adapter + a Logitech wireless mouse.
I messed with Knoppix and like it, Ubuntu, like it but had difficulties....
PClinuxOS is what I’m using right now. It’s detected everyting, runs well, and boots in half the time of WindowsXP.
My son’e laptop was crashing several times per day until we put PCLOS on it, and it’s been rock solid since. That inspired me to dual boot mine.
