In case you missed it, Psystar's new downloadable software lets you install OS X on any PC with a Core 2 Duo, Quad, i7 or Xeon Nehalem processor. CrunchGear tried it on an HP TouchSmart, and even the touchscreen worked.
Turns out the OS X install screen takes ages to come (they thought it had crashed), but with some patience they had themselves a hackintosh.
Psystar says the $50 download allows for the permanent installation of multiple operating systems on a single system, and that it works with Windows 7. You'll still need your own copy of OS X.
A trial version is available (with a 2 hour time limit), and comes with all the expected warnings of them not being responsible for you losing your data should thing go awry.
Of course, you could also use an open-source EFI bootloader like Chameleon. A good alternative if you're command-line savvy, and not a fan of Psystar. [Psystar and CrunchGear]
