As a long time pc user I used to hate macs... till I spent a year supporting them for verizons DSL service. Most pc users just dont know a lot about macs and there are more sterotypes in this thread than I have seen in a long time.

Keyclones issue is cost vs reward. He doesnt have a mac to dev it on nor 2 to test it on. He is a smaller company and unfortunately just doesnt have the resources of M$ or Apple.

Try the dual booting options others have mentioned... or... send Rob 2 macs and a dev kit =)
