True, mind it would be a lot faster than anything a have as its the dual
2Ghz G5 mac, so its a wee bit quick. I'm not sure just how much is 64bit
myself. I'd like to hope that most of osx is but as its based on freeBSD 5
so I just don¹t know. I know the machine can handle 64bit apps but I have
never found the need to, unless all of a sudden M$office, mozilla and Adobe
Creative Suite have suddenly gone 64bit?? heh
