Go on to Amazon and look for Windows 7.
You've got "Microsoft Windows 7 Home Premium, Full Version" for £106, "Microsoft Windows 7 Home Premium Upgrade Family Pack for XP or Vista users" for £129, "Microsoft Windows 7 Ultimate, Full Version" for £170, "
Microsoft Windows 7 Home Premium, Upgrade Edition for XP or Vista users" for £165, "Microsoft Windows 7 Professional, Full Version' for £150 and so on and so forth.
For Mac OS X there's two versions, a single license for £20 or a family license of 5 copies.
As said one box, one price, all the features.
I like Windows and consider myself to be reasonably technical yet I get flumoxed when someone asks "so what version of Windows do I need?"
If you're going to say that Mac OS X is complicated because you sometimes needs the latest version of the program then you have to say the same for Windows. And for each version of Windows there's at least 6 times the packages as there is for each version of Mac OS X.
Comparing "latest version" to "latest version" has Mac OS X being simpler. Trying to consider other versions makes Windows look exponentially worse. Add one version of OS X, add at least 6 versions of Windows.
Windows pricing and packaging is complex.
Mac OS X pricing and packaging is simple.
And I say that as a relative Windows fan (for certain things), it's really rather inarguable.
I also say this as someone who's in the main a few versions of Mac OS X, and one serious hardware revision, behind the loop and yet doesn't really have any major problems.
I'm not saying that everthing in Mac land is wonderful, it's not. But I know that when I buy a boxed set of Mac OS I get everything, unless you pay a lot of money you simply cannot say the same for Windows.
