Are you ready to upgrade to the latest version of OS X, Leopard? Great. Here are the versions available to you today. Select carefully, as only one of them is right for you:

• Mac OS X Leopard Home Basic
• Mac OS X Leopard Home Premium
• Mac OS X Leopard Business
• Mac OS X Leopard Enterprise
• Mac OS X Leopard Ultimate

And if you plan on installing Mac OS X on more than one computer in your house, you better be even more careful about which edition you decide to purchase. I would recommend the following for those of you with more than one Mac in need of a Leopard upgrade:

• Mac OS X Leopard Family
• Mac OS X Leopard Family Small
• Mac OS X Leopard Family Nuclear
• Mac OS X Leopard Family Retired
• Mac OS X Leopard Family Adopted

If you still want to run Windows or Linux applications on OS X, you’re out of luck. Unless, of course, there’s some kind of magical software out there which would allow you to run those programs in Parallel. Gee, wouldn’t that be awesome? Yeah, and maybe pigs will fly out of my PC’s floppy drive.
