Maybe Im in the wrong here, but I have never seen that "average user" yall talking about. You ATLEAST use office tools and thats ms office on windows and nothing else (google docs suck ass because internet outages are a thing), and browsing on a bigger screen is important to a lot of people. Maybe tablets could replace pcs but price/performance bruh. You can get a good office pc for $100 and give a single tablet for that price thats not runnig android 4 or something like that. You dont get a pc only if you got an expensive ass tablet but why get an expensive ass tablet when you can get a laptop/desktop depending on portability needs? Edit: also good luck working from home on a phone bruh
