I started with a windows pc and considered services like macincloud for remote osx access. I determined that option wouldnt work, so purchased a cheap mac mini. This worked, but it was a pain. Building and testing on 2 computers is not fun. Just because it works for ios on the chrome emulator on your PC doesn't mean its gonna work on a real iPhone.
I bought a macbook pro, and life is much better. That is my advice to you.
