If you're an existing Mac user, the recommendations here to "just get a Mac" may be better, but I'll throw another possibility into the mix: I ran OSX in VirtualBox for a good while in order to use some locked-in iOS dev tools. It was slow, but that was largely just because my underlying machine wasn't very new at the time, it was easy to install, and I never encountered any stability issues. It would free you up to get the best machine without worrying about hw compat. Disclaimer: This was OSX Lion days. Have not tried recently. Ymmv.
