Personally I think that Apple should compile Darwin for the x86 (come on. Don't us I*tel, AMD will kick their ass anyday) because then developers will be able to compile their software on a variety of platforms and be able to test them before releasing them to the public. They could inclused the FreeBSD driver packages and with minimal tweaking hand it over to the public to fix up.
On another note, does anyone know where I can get a real cheap G4 setup. Under $750. I don;t need RAM, Hard Drive, Vid Card, Monitor. Basically jus tthe Mobo, case, and processor. I will add the rest myself. really need a mac for school. Help would be appreciated.
