It's possible, but whether you actually want to and have the know-how is a different matter. I would assume that the cost of a used MacBook or Mac mini would end up being more cost-effective in the long run than finding any other way to develop apps for the iPhone in terms of the time it will consume. For what it's worth, I have some friends who bought a Mac expressly for iPhone development but when they're not doing that, they use their prior computers and run Windows in bootcamp. If you are really dead set on not buying a Mac, then http://arstechnica.com/journals/apple.ars/2008/11/11/developer-creates-app-store-game-on-windows http://arstechnica.com/journals/apple.ars/2008/11/11/develop... There is also osx86, but if you run into any problems either with the above suggestion or a hacked version of OS X to run on non-apple hardware, you're pretty much screwed, especially if it doesn't happen on "legit" installs. Apple won't support it (you do get a couple of opportunities to get code-level help from apple engineers with the iPhone dev program), and neither will most people you encounter on forums/mailing lists due to all the little complexities of running an OS on unsupported hardware. Lastly, what's up with the "trendy"? I just use whatever works for what I need. For the iPhone, that is a mac. Getting a mac for iPhone development only makes me trendy in being an iPhone developer, but still I'd be getting it because I needed it. There is no shame in that :)
