Why can't Mac breakdown like Windows ?

With the release of the MacBook Air (http://www.apple.com/macbookair/) , Apple's innovative creations have reached a new zenith and quite predictably we once again gossiped about Apple's product and pretty soon landed on the MacOS.

Their powerful, sturdy and super fast operating system -MacOS, has yet another feature - it never hangs, unlike the famous, userfriendly, nice Microsoft's OS - Windows.

An obvious question is - "How come MacOS never hangs or breaks down?" . I put this question to a friend of mine, a noted armchair critic !! He replied -

"See, have you ever tried to install a MacOS on an assembled PC ? Well, even if you try so, it would be futile, waste of time and money. You cannot install the MacOS on a PC, you have to buy that beautiful, stylish, powerful and COSTLY Mac computer to run an MacOS, that is, a MacOS runs only on a Mac computer. So, you chose your own hardwares, your own chipset, and you develop a OS that runs only on these hardwares, so how can it hang ?
This is what Apple does, they market their own brand of computer under the name Apple Mac which has handpicked hardwares, chipset and they develop an OS called the MacOS (the latest being the Mac OSX Leopard) which runs only on this hardware configuration - the moral - u take a book, measure it properly, buy a huge sheet of paper to cover the book and cut the paper according to the dimensions of the book - how can the cover NOT fit properly ? ...analogically - how come the MacOS hang ??
On the other hand, Windows - you purchase any arbit hardware from any shop, build your own crappy computer and get a Windows OS - it will beautifully run in that contraption that you have developed ! the moral - you take any book, and take a BIG sheet to cover the book - the cover will fit the book even without cutting but will have some loose ends ! ...analogically - the Windows can run in any comp, the problem - it will have lots of loose ends that may make it go berserk and in the end - it hangs !! also, that is why Windows has a very BIG ,complex and abstruse code. "

A very neat and neutral opinion !! However, the recent Mac OSX Leopard can run Windows as well (http://www.apple.com/pr/library/2006/apr/05bootcamp.html) !! . So, effectively, I can purchase an Apple Mac (if I can afford one!) and run a Windows Vista in it !! Am an Apple and Microsoft customer !!

However, Apple's computer have now shifted to the Intel based chipsets ---Apple's a real revolution in the Electronics world - a apple a day makes you bankrupt in a day --- some comments I heard about Apple.
