The true power of Linux is in its near-infinite variety: no matter what your particular requirement, the chances are that you can find a distribution tailored to your needs. There are Linux distributions aimed at power users, programmers, gamers, people moving from Windows and those with older hardware that just isn't powerful enough for many modern operating systems.
It's this last market that Puppy Linux, a lightweight distribution created by Barry Kauler, targets. Unlike more 'mainstream' distributions like Ubuntu or openSUSE, 'Wary' Puppy Linux is designed to work on as wide a range of hardware as possible, regardless of its age or specification.
In addition, the Puppy Linux project creates various other distributions including Slacko Puppy - based on Slackware, and compatible with that distribution's binary files - and Lucid Puppy - based on Ubuntu, and again compatible with Ubuntu-derived packages.
