I've been playing with Yellowdog Linux on my powerbook. I got the machine because OS X runs Word which is a requirement for the business environment. If your RMS you can ignore those who send proprietary documents but unfortunately I don't think my boss would be too impressed if I did it. So the laptop is for work ... just work, and I absolutely promised myself that I wouldn't use it to hack around on but I fell into bad ways and loaded Linux on it... dang!
Let's not get into the whole 'why would you load Linux when Mac OS X is so much better', I'll simply say that I miss Linux. Yellow dog linux rulez, well it certainly does what it says on the tin. Using Linux on Apple reminds me of my first Slackware in 1996 - on a book of the same name. It's not really suitable for people who think Linux is only free if your time has no value, but it works with a little effort - even putting the laptop to sleep!
As with any small distribution, and on an odd arch you don't get as much variety of packages. The goings on at PlanetGNOME made me want to try some of the new stuff coming down the track. Last night I downloaded Garnome and set it to compile the whole system up. It really is pretty neat, I've had to load up some additional libraries but it does make amazingly short work of the whole thing. Of course the last time I tried something similar using the vicious-build-scripts I was on a dial-up so maybe that made the difference ;-)
Oh, and since there's a blog tool called adventurously gnome-blog on the panel so I had to try this little test!
