If you operate on a sealed system without outside connections, using only hardware from the tested and approved list, install it properly, and only install applications (never updating them, of course) from the tested and approved list, then I suppose it's a reasonable requirement of expecting a bug-free system.
If you never update you never plug the holes in the OS and I wasn't referring to Hardware Patches above but Security Patches which are what is released during the Monthly Patches by Microsoft.
Not really sure where the reference to Apple comes from or at least that is the way I'm reading your bit above as they are the only company with a Closed System on Restricted Hardware that I'm aware of.
The above post was in response to a post which clearly said
Us guinea pigs have downloaded and run the various iterations of W8
since last fall. You are NOT a guinea pig. You have the option of getting a massively tested OS for a minimal fee.
I was just pointing out that 8 is no where near as Massively Tested as the poster was claiming and they with previous Microsoft Releases there are massive problems present when the system is released. It's not a uncommon occurrence for most IT Pros to say that you never load a new Microsoft OS in a production environment till the first Service Pack comes out at which time the worst of the problems have been addressed.
As far as I know that is still the firm belief that is expounded by everyone working in IT except Microsoft.
