The world of technology moves so fast that it often breeds rumors of death that are greatly exaggerated. No sooner does a particular market pick up--like the ones for smartphones or tablets--than various pundits pronounce that previously dominant markets or dead. This tendency didn't begin with the transition from mainframes to personal computers, but that transition is as good an example as any for why people are son prone to pronouncing big market players dead before their time. In the latest spin on this phenomenon, many are wondering if the PC is dead. The answer is that it isn't.
