So grab the OpenDarwin ISOs, and you've got a working machine. Or any of the Linux variants that run on PowerPC.

Or hit Froogle, and find the Mac OS X 10.4 install media for under $75.

If someone gave you a PC, how much would it cost you to get a license for Windows to install to use it, if you weren't going to Linux or some other free OS?
