Is the PC dying?
Not a moment too soon...
What a fad!
Bottom line is this: I think the traditional PC is on its way out. (And with it, of course, the device that spawned a gazillion forums.)
If the PC is on its last legs, or beginning to wobble like a drunk headed for the curb, I'd like to say, "thank goodness!" Take a step back from these past 20 years, and what I want to say is this: What a horrible way to spend one's life! Sitting in front of a computer screen, looking at some CRT or LCD rather than into a real person's eyes.
These past decades have been just sad, in human terms.
