I think we’ll see the end of the PC era when all demand goes away. Right now, I just don’t see that happening.
Sure, there’s likely a larger market for the latest and greatest cutesy/novelty items. Serious computer professionals need serious computers so I suspect (hope) that doesn’t make traditional desktops and laptops “go away”. If they do, that’ll be the indicator that it’s time for me to retire, or just speak for a living. 🙂
