I think that Apple makes it pretty easy for iOS developers to port their existing work to become Mac OSX apps offered up on sale in the Mac App Store. This is pretty cool and it gives diligent iOS app developers some form of first mover advantage. Case in point would be G5 Entertainment.

They have ported not one, not two but EIGHT of their games, some of which are heavy hitters well received by iOS users. Check out the following press release to find out more about this massive launch:
