Do you have a Mac? If you do, and you’re not sure what to do with it, why not try Yellow Dog Linux? Consider this a testimonial. I love YellowDog! I’ve used LinuxPPC and Mandrake on my poor old Powerbook, and YellowDog is bar far the easiest to set up and use. It’s based on RedHat 7 (so it’s reasonably up-to-date) is easy to update (thanks, yup!), fairly easy to configure, and runs like a champ. You can even dual and triple boot between it, OS 9 and, if you’re crazy, OS X. Does it GET any more fun than that? I thought not.
