people having problems with hackintoshes are 'doing it wrong' if you have the right hardware then it will be exactly as stable as the apple equivalent
before i got my macbook i ran a hackintosh for around a month on desktop and netbook . partly because i was bored and like fiddling and partly because i wanted to make sure i was ready for OSX. the netbook would have been great if the cpu wasnt so weedy. even the 3g internet on it worked!.
Well that's the whole point - you buy it and it works, you don't spend time fiddling and you have time todo the important things that pile up..
If you have time, or enjoy fiddling as a way to spend your free time then Linux is better suited
