The best line in the article:

(Despite this, I will speculate that today’s single-threaded applications as actually used in the field could actually see a performance boost for most users by going to a dual-core chip, not because the extra core is actually doing anything useful, but because it is running the adware and spyware that infest many users’ systems and are otherwise slowing down the single CPU that user has today. I leave it up to you to decide whether adding a CPU to run your spyware is the best solution to that problem.)

Adware? Spyware? What are these things of which you speak, asked the OS X user.

I like the idea of multiple CPUs. It lets Windows worms and viruses spread through your machine much more quickly. (Insert smilie of rolling eyes here.)
