Knoppix as a hardware testing and Windows rescue tool.
This is a marketing suggestion rather than anything else. Why not encourage OEMs and motherboard manufacturers to include a Knoppix CD with every motherboard, OS-less PC, and Windows PC. It is useful for testing of hardware independantly of Windows, recovery from damage to NT bootloader, damage to filesystems and partitions, repartitioning etc. It is also useful for OEM support - instead or trying to troubleshoot an unknown Windows setup, the OEM can ask the user to insert a Knoppix CD to get a standard configuration to troubleshoot. The OEM can also add his own custom tools to automate support and troubleshooting.
Once Windows users try Knoppix, I am sure they will be converted for good.
