Nicholas Blachford has written an interesting article that discusses the difference between x86 (pentium and such) processors and powerpc processors. Sure, I've seen such articles before, but they were all biased. Even though this particular article was written by someone who works for a company that develops PowerPC based motherboards, and an accompanying Operating System, I couldn't find anything that looked biased.

If you run an x86 (pretty good chance there), and think it's perfect: read the article. If you have a ppc and want to know why it's better than the neighbour's x86: read the article. If your nickname is JJJ: read the damn article.

Thanks to Felix for the link.
