I used a hackintosh for a year for development. It took a day to setup, which is of course a lot more work than for a typical osx experience. However, once setup it was better than the mac pro I was using. Might have even been more stable. Upgrades were a bit of a hassle, but not horrible.
nah it's not bad. Sometimes you just need to reinstall the same audio kernels, etc (depending on your hardware). There are many guides to find compatible hardware
