Most modern motherboards support booting from USB devices and you can easily change your boot order to enable booting from USB drives. If your motherboard does not support USB boot you can very well format the drive and use it as a normal flash drive :). At present we are offering Ubuntu as the only Live USB Thumb drive. In the near future you can expect to see Live Knoppix Pen Drives, Live DSL Pen Drives and Live SLAX Pen Drives.
