If you are going to go fulltime dev for iOS might as well buy some kind of mac to run it on, perhaps see if it can be done on a mac mini or buy refurbished to save some money http://store.apple.com/us/browse/home/specialdeals/mac?mco=M...

You say it is relatively inexpensive, so if you have that disposable money you won't have to worry about getting locked out later for some reason if hackintoshs are found and banned.

If you are doing it for fun though might as well try the hackintosh if you already have the hardware, though it isn't condoned by apple.
