Over the years I have used Slax far more than any other distribution for rescuing windows systems or retrieving data off a drive with a broken OS. I love the fact that you are root throughout, including having write access to all drives and partitions.
I've been able to simply copy a good C:\boot folder over a corrupted one using Slax, a 5 minute fix that doesn't require having the install media. (which few people have anymore thanks to cheap manufacturers trying to save 5 cents)
I've made more money using Slax than any other distribution. I am forever indebted to Tomas M for both Slax and the Linux live-scripts he created, making a "live" system possible in the first place.
I have a USB drive that has my own, persistent /home partition on it, so every time I boot the live CD I have my own desktop, with my own tools. No other distro is designed to do this, to my knowledge.
I also installed it to HD on a few of those older laptops, I gave several laptops to children who's family couldn't afford a computer, an old P-II or P-III is still quite useful with Slax on board, and safer than if you tried to run the windows 98 they were designed to run originally.
BTW I use Slax 5.1.8.1, the last fully mature release, in my opinion. I never had much luck with Slax 6.
