Activating Windows XP

I have been thinking a lot about Windows XP lately and my own thoughts on Product Activation. I was reading an article in the latest PC Gamer about how quick and easy it was, and I decided they just missed the point. Years from now, I can put together a new computer and load 95 or 98 or Linux or whatever I choose on it. But what happens when Microsoft decides to stop giving out the matching code numbers for XP. You are totally at their mercy and they can stop whenever they choose. And that is why XP is not for me.
