If OS 4.x were made to run directly on x86/64 hardware, would you buy it?
I can't see any reason to why I would ever buy OS4, no matter the HW, so I voted no.
But having it running on proven 2011 level HW costing $250 is of course better than having it running on obscure and unproven 2007 level HW costing $2,500... :p
