New/crazy names don't work...
Interesting. I definitely agree that consumers are not loyal anymore (nor should they be).
But I don't think Nokia changing their name in the US would work - for one thing its been tried before by Philips (Magnavox in the US) and others with little success. The bottom line is that Brand quality is more heavily influenced by the substance of the products than the other way around.
Consumers aren't dumb - or they don't stay dumb forever;-) and they tend to pick based on their needs and sense of value. People (especially Product Developers) often think this sense of value is wrong because it ignores what they consider important, say features or technical specs.
But actually consumer markets are pretty good at spotting the product that offers them what's important to them. The trouble is, the balance of their priorities, between features, specs, style, affinity etc, change often, making it tough for companies to keep up.
Bottom line: Nokia phones have been behind the times in the things consumers consider important. We might love feature X of Symbian but consumers don't give a toss. Changing a name won't do.
And similarly don't expect the current leaders to stay in the lead if they fail to keep up with consumer priorities. Apple spent a long time as a tiny nice supplier of nice products and Samsung was considered a low end phone maker for almost as long because they were failing to match consumer desires. Nokia could rebound on the back of Windows Phone or fail utterly, but it will depend on a combination of what they do and what MS does.
I seriously doubt MS is placing their hopes on HTC and Samsung though. These two are THE champions of Android and MS did just pay $250m to Nokia...
