Laptop Hunters Ad Hurting Apple? Kind of...

"Microsoft's "Laptop Hunters" ad campaign focuses on the price difference between Windows PCs and expensive Apple Macs. The commercials have raised consumers' perception of Microsoft's "value" -- and have hurt Apple -- according to YouGov BrandIndex, a research service."

Something struck me as odd, and reading the comments on the post, I found it:

"Yeah, good point, Dan, the wild swings in the graph from one extreme to the other, would tend to make this graph somewhat questionable. Honestly, does perception of value change THAT much over such a short period of time? Can we see other comparative graphs of other companies? Can they correlate it to anything?"

That is indeed an interesting question because the run of the ads doesn't seem to correlate with the "dip" in value perception.  I'd be interested to see other value perception charts as well.  I'm not saying the interpretation of the data is wrong, I'm just not sure if that interpretation can be made with the amount of data given.
