Other than NetBSD, I was not aware it's "easy" to run other OS's on Apple hardware. Knowing Apple, I'm still not sure I believe it.
But I will investigate. Thanks for the FYI.
The PowerPC macs are a bit less well supported just because there are fewer distros for PowerPC, but on the other hand, since apple's pretty much abandoned them, going with linux or a BSD has its own advantages
I run linux (arch now, but once ubuntu) on a MacBook5,4. It's somewhat harder to get set up if you want to dual boot (the dual partitioning scheme is finicky, and although linux doesn't need it, OS X forces you to use it if there's a foreign OS, ugh..). See http://wiki.freebsd.org/AppleMacbook and https://help.ubuntu.com/community/MacBook .
Only one proprietary driver (for wireless) is needed - the rest Just Works. (And flash plays smoother than on OS X :P )
Or maybe bootcamp could mention Linux.
This works well for me with PC's. Would this work with today's x86 Macs?
What you can't do (Apple say) is run Apple OSs on non-Apple hardware.
