The PC is dead
The "RIP PCs" article is one down:
First it reports the Gartner projections, then it points out some of their limitations, e.g., counting all Microsoft OSes for all devices in one pot, and all Apple OSes for all devices in another.
Obviously neither the title of the article nor yours are to be taken seriously, being attention-seeking sensationalism.
Both gamers and serious workers will always need the extra power that only an extensively cooled PC workstation can provide.
