I think I now understand how to do it. My host OS is Windows 7 Pro x64. Do I want to buy a Mac system. Heck no. Mac OS = cheap, Mac hardware = expensive. Windows OS = expensive, non-Mac hardware = cheap (compared to Mac). But I want to learn the OS, even though as simple as Mac OS X sounds, maybe there's nothing really to "learn." But I want to become familiar with it, cuz if I get a job that uses all Macs, well, I'm up a creek. But, I can NOT for the life of me find anything about the cost of Mac OS X Lion for a non-Mac user. I know it can be done, cuz how else would people be able to put OS X on VirtualBox on their Windows-hosted machines... So, understandably, it's $30 if you have a Mac and I think that's also if you d/L the OS from the website. But I can't find out how much the full version costs. So if anyone knows, plz let me know. Thanks.
