Recently, I tried PCLinuxOS via the "live CD" route. I downloaded the .ISO image of the CDROM and then used Nero to burn the image onto a CDR.

You can download it for free. You can burn it to a CD. You can boot your computer from the CD. And, you can see what PCLinux is like without ever installing it on your computer.

As I played with it some more, I discovered something that I had missed when I first tried it. PCLinuxOS will start booting and then will stop at a menu that gives the user a number of choices. Like many boot menus, though, this one is on a timer — if you don't respond in time (and I didn't, since I had started the boot and walked away), it selects the default and runs PCLinux from the CD.
