I tried searching but didn't see anything. I have a 1.83 Core Duo and 2.16 Core 2 Duo. My 1.83 has all my music, programs (that I don't have install disks anymore), and my docs. I want to get Lion and wanted to know if I can swap hard drives between computers? I think it will work fine but let me know if there is anything that I should be aware of. I have back up drives so minimized risk of loosing data.
