I think the death of the PC won’t happen until phones and similar have the same power user capabilities as one. As long as we need a PC to build things for our phones, they’ll exist in some form.

The PC for everyday regular usage though is indeed dying. My girlfriend has an iPad Air with the keyboard case from Apple and it’s her primary computing device!

Not death of the PC! Just the presence of more numerous and cheaper smartphones. They're superior to PCs for most people but not for everyone.
