Don't you want brand expansion into the general public consciousness beyond more than simple jingles and nerdish images ?
It's an interesting question, but the answer isn't as obvious as it might appear. The idea that you can (or should) keep evolving your brand in order to keep picking up incremental brand loyalty seems like a great concept but sticking with my Caterpillar analogy, if CAT starts a hip marketing campaign with sleek, theme colored machines (like maybe a pink one for the female operators!), how many construction buyers would raise an eyebrow and start looking at other names? Granted this analogy is a bit extreme, but perhaps nerdish images and simple jingles is just the place where Intel needs to be. Sure we all want to be sexy and cool, but please Intel don't risk any of our 40 billion in revenue just for that. So as a shareholder I'll leave the brand management to those that are paid to analyze, measure and take care of it.
