iPhone development on Windows
Is there a way to develop iPhone applications on Windows?  I really don't want to get yet another machine.  

There is a project on http://code.google.com/p/winchain/wiki/HowToUse that seemed to work with iPhone 1.0, but had limited success with iPhone 2.0, plus it requires all the cygwin insanity.  

Is there anything else, or do I have to buy a mac?
