While 3 years old, this article says Apple spend $287 million in advertising in 2005, and that was part of an upward trend. http://news.cnet.com/iPod-ads-cost-Apple-a-bundle/2100-1047_...

In comparison, the Vista campaign is reported at $300 million today.

I think we can say that Apple spends comparable money on advertising as Microsoft.

I don't think this is necessarily a bad thing, but it does make this particular commercial annoying and misleading; a big disappointment from the clever ones that began this ad campaign.
