For those who feel that having a Mac can help doing a better job or inspire in some sense while drawing, composing music or simply reading e-mail, a hack is now available for PC. They call it FlyakiteOSX. It's an interface emulator that goes a bit deeper than just substituting your theme. Personally, I'm using it for several days already and still have no intention to remove it. The first step towards buying a white piece of equipment is taken :) "You make your choice and you live with it."
