Oooh, ad war escalation! You remember how Microsoft got so mad about Apple's ads that they had to run out and spend $300 million on a fancy ad campaign consisting of Mac lovers declaring their love for PCs, as well as celebrities doing things seemingly unrelated to computers. Meanwhile Apple has just been sitting back chuckling, and now they've released a new ad making fun of Microsoft's ad spending. Which is too insidery, but very entertaining to people forced to write about ad campaigns. Apple's only problem: the people who buy PCs, such as myself, don't even know what this "Vista" thing is. (If we knew about computer things we would have bought a better one!). I imagine that Microsoft grows ever more apoplectic, though. Full ad below:
