In light of the fact that PowerPC is history, consider the following: I currently own both a 2.0 G5 Power Mac (second generation., best computer I've EVER owned) as well as one the last iterations of the iBook G4 laptop. Wondering out loud. . . Now that Apple is full speed ahead with Intel, would this mean that possible virus/worm/trojan infections would be practically nill with regard to this "older" technology? (security by even more obscurity?) (Apologies if this has been talked about previously...) Your thoughts and comments welcome!
