Because if you don't update, your mac becomes obsolite, you can't install software updates. Heck, there have been people that had to buy a new mac if they wanted to get a new iPhone or iPod. That's never been the case with Windows.
What are you talking about? You don't make sense. Windows and Mac OS X apply software updates the same. You can't slap Windows 7 on a Windows 98 box & you can't slap Lion on a Panther box. So, you are wrong Windows and Mac are the same in that regard. There is a hardware and software compatibility limitation that all devices are subjected to.
At least when it's time to upgrade software Mac OS X costs a few dollars and there is one version to buy, but Windows costs hundred of dollars and you have a bunch of confusing versions to choose from. Why can't it just be Windows?
BTW you can upgrade Mac hardware you have to know what you are doing.

Ummm it's an accessory. By definition you can use the tablet without it. You apple lovers are certainly getting desperate with your arguments.
They why did Microsoft spend the major of their Keynote on it? Because, it's the game changer feature, so yeah you count it, because when you buy a Surface you will be lugging around it's keyboard... period. Have fun with that.
