The day that Snow Leopard came out, I decided to by the box set because I didn't have iLife or iWork 09 yet. I'm about to purchase a MacBook pro, and I was wondering if I would be able to use the iWork disk from my box set with my MacBook pro even though I already used it on my MacBook. The box set applications never make you enter a serial key, so how does it keep track? Will I have any issues (LEGAL ISSUES or ANY OTHER ISSUES) if I just use that disk or do I need to purchase a new copy? Thanks
