Again, I think it's a horrible idea to run Windows on Mac, if you want to use Windows go buy a Windows machine, not Mac.
And if you want or have to use both Windows and Mac OS X?
It is your prerogative to believe that a Mac running OS X is called a Windows machine, though wrong.
It is not my believe to call it anything. Both Windows and Mac OS X run on computers sharing the same hardware components (CPU, GPU, ports and so on) and only differ in small areas.
I do not need to call a computer running Windows a "Windows machine" and do not need to call a computer running Mac OS X, or OS X nowadays, a "Mac machine". Both are computers, and nowadays one simply has to say "PC" for a computer running Windows, albeit the wrong term for it, but we strangely live in computer illiterate times. The word "Mac" for a PC running Mac OS or Mac OS X or OS X or System 1 through 7 is another area, since those computers were born with that name and were a little bit unique using a different architecture than Windows based PCs until the Intel switch.
Taking it for granted? That just doesn't make sense!
You said something about not taking something for granted (check the quote in my post) and then I replied, that I do not take anything computer related for granted. I worked with enough Windows and Mac OS X based computers to have seen them fail and fail again, due to some ****** software on it or some hardware connected to it (even if being a verified workstation) or the OS just frelling panic.
Try boot up time, try open up Firefox. You decide which one is fast which one is slow.
That is where the opinions differ. I am of the opinion, Mac OS X starts applications faster and boots up faster, but I also have seen well maintained Windows based computers (writing "PC" is probably simpler, but I am quite an arse that way) being able to boot faster and start applications faster, though Windows Explorer seems to be the exception. I am always too impatient and press Windows+E too often and end up with five or so Windows Explorer windows open.
You should not twist a fact and insist it is an user's opinion.
What was that fact again?
A computer is there to be used, and if it is possible to install any compatible OS on it, then it can be done. Just because a computer was initially built to run primarily one OS (that Windows based computer from Costco or that Mac from Best Buy), does not mean, it has to be that way, especially if the needs differ.
This is a circling discussion, isn't it? And not one of those other bastards out there are keen to chime on. Cowards. Probably have something better to do, like watching Katy Perry frog a kegel.
