I just wrote a very long and pointless comment trying to express this very idea. It's not that the PC is any more interesting than it has been, it's that a lot of interesting things are happening in tech, and the PC is the way to access them.
It's like saying that cars are interesting again because the city built a new stadium. No, the stadium is interesting. The car is just how you get there.
