You can carry GNU/Linux in your pocket with a functional, quick, and useful USB pen drive distribution. Pen drives are faster than CDs, and the small distros that fit on them don’t require huge amounts of memory for the operating system and applications. Slax is a powerful and complete bootable distro based on Slackware, equipped with kernel 2.6, ALSA sound drivers, Wi-Fi card support, X11-6.8.2 with support for many GFX cards and wheel mice, and KDE 3.4 Link.
