Seems like an obscene amount of computing power for a personal computer. Who is pushing their desktop that hard? Majority of people just want to send/receive emails and write a document.
I know this is meant to be sarcastic, but it's a perfectly reasonable point. Not only that, it already came true; a lot of the time compute power has become so plentiful that we're more concerned about battery life and efficiency than actual raw grunt in personal computers. The main exceptions are gamers and people who use productivity software, but let's face it: Grandma does not need a 7995WX to log into Facebook.
I’d go even further, at least anecdotally - most people don’t seem to have a desktop or even laptop computer these days.
Literally none of my non-techie circle own a personal desktop. Only a few own a personal laptop - and even then, it only gets turned on occasionally. Most of them do all their personal computing on an iPad or smartphone.
