John Biggs has a Psystar. It’s a generic PC that runs OSX Leopard, and runs it well at that. It was roughly $550 shipped, and there’s something that gives one a sneaky feeling when using it, as if you’re getting away with something.
The Psystar, though, may be just the tip of the iceberg. Apple Insider points out that there are now other PC clones running OSX, and you can get them on eBay.
Of course, you can get your own PC and install Leopard on it using the same patches and hacks Psystar does, but where’s the fun in that?
