[Slax] What makes Slax different? Size. Slax fits on a mini CDR so it’s easy to tote it around with you. You can take your operating system with all the familiar apps with you to any PC that has a CDRom drive and you can reboot. At your parent’s house with their computer full of AOL and bloat? Pop in your Slax and get some work done. Company laptop that you can’t install things to? Pop in your Slax and bypass it with your own desktop OS.

While I still prefer the idea of Portable CE or a VM with XP Embedded on my USB keychain, Slax is a pretty cool (and complete) distro that can fit on a mini-CDR. I’m betting it wouldn’t take too much work to get it on a bootable USB device, either.
