I'm with MTK. I run SimplyMEPIS 6.0. Totally free, works straight out of the box, detected all my hardware, and tons of apps. You can run it in RAM as a LiveCD to see what it's about, then go for the install. But do read about what you intend to do first.
I triple boot with ME, XP, and SM6 as default. It's not meant to replace Windows: it's an alternative OS that gives you control of your computer back. You'll lose nothing and stand to gain a lot just by running the LiveCD.
