Psystar is perhaps going a little too far here? Today, they've announced that they aren't just selling Mac Clones. They are certifying other maker's PCs for their new virtualization technology for Snow Leopard - effectively making their systems Mac OSX compatible.
They are touting a technology called the Darwin Universal Boot Loader (DUBL) and will have three versions: Desktop, Server or Mobile. Once a product is certified, consumers can purchase it off the shelf or through standard channels and when labeled Psystar Certified would allow the installation of Snow Leopard simply by inserting the retail OS X DVD. They also tout a separate "Safe Update" program which will allow special versions of the software updates to be pushed.
Wow, this is certainly big news and a new direction
