I have a new iWorks program and after loading it on my Mac I was wondering what would happen if I put the disc into my PC with Win 7 and tried to put the word processing program on the PC. Would like to use it on both computers. Boy this will get me picked on for sure. Some one will say just put it into the slot and see. But it might kill the Dell dead on. Just wondering...I know MS makes Office for Apple, does Apple make programs for MS. Dah
