I'm just waiting for the LeOSX86 version (Leopard OSX86 - Hackintosh) to be released so I can install it over the top of my OS X Tiger partition (my laptop quad-boots Windows XP, Vista, OS X and Fedora Core 7 Linux), there's instructions on how to patch the retail Leopard DVD on various forums but I'd prefer to get the stable install discs when they're available, the first is due for release tomorrow (27th).
For those who don't know, Leopard is the newest version of the Mac OS - preview trailers are here - http://uk.youtube.com/watch?v=mYmuI4typJA.
