So, I installed
linux on my iBook. Went swimmingly. Sound, GL desktop, networking, bluetooth, etc - everything perfect and running fast as you like - snappy, even, for a G3-800 (with the single exception of g/qsynaptics not working quite right - although the touchpad still worked fine, I couldn't do fancy multitouch/scroll stuff)
Until. I need Skype, because just about everyone I know insists on using it despite it being proprietry, and shit. No PPC-Linux build of skype available. Force-architecture install doesn't work. Bugger.
So, am now back on OSX, back to swearing at my file manager 'cos it won't do even the most basic things. ffs.
