How cheap do you want that computer ? Because pretty sure you could get an older Mac. Also -- HTML5 and Javascript-level frameworks such as phonegap.com seems to gather some following. You might want to look into that. I've written a few apps and even published a few but, in retrospect, none were so complex that I really needed to use Objective-C. As long as you have access to all the features (ie. camera, accelerometer, etc) Javascript might be the way to go. The only situation I think you really need Objective-C is for the Open GL ES part but rumor has it that the canvas on Mobile Safari uses that. In conclusion, I think using a Hackintosh to develop for the iPhone/iPad might be just a way to find yourself a challenge, unless you plan on using your existing PC-hardware. Buying new PC-hardware instead of a mac isn't logic. But the side conclusion is that using the SDK itself might be unneeded for most of the common apps.
