An update on my progress, of switching to GNU/Linux…
I now have a really stable machine, I had a few problems with the internal sound causing the machine to lock up when it would try and ‘beep’ at me – fixed this (for now) by removing the snd-powermac module from /etc/modules
I can now play all my music, still using free software, thanks to Rhythmbox and VLC.
Evolution is a really good email client.
Nautilus is my browser of choice.
