- It can be installed to a hard drive if desired. The install is amazingly easier than the regular Debian install process.
- It is based off the Debian distribution -- when installed to hard drive it becomes in all respects (except hardware detection?) a normal debian installation.
- It is reputed to have some of the best hardware detection of all of the Linux distributions.
- It is available for free download and is easily burned to cd-rom.
- It is apparently relatively easy to modify to create special purpose versions or different collections of software packages
- It seems to be becoming quite popular.
peterc: It also makes a fantastic Linux rescue disk, with one of the best hardware auto-detection systems around.
