hey all. i want to get this but i dont know if it will work with my computer. it says that you need a 500Mhz G4, i have a 500Mhz iBook G3 but i have everything else that it requires. i cant imagine that it requires altivec because then it would just require any G4, and that it states that it needs one that is 500Mhz, does that mean it wil not work with a 600Mhz G3? the short end of the stick is, will this thing work with my iBook? i dont care about speed, i just want to burn some dvds so that i can back up a lot of info and such. thanks for any info.
