Well.. the majority of people is most likely unable to use the potential of a PC. It`s far to complicated, expensive, huge and nerdy.
Most people I know, use PCs for organising via Outlook, writing letters in Word, organising address data in Excel (yes, not in Access.. :>), and some more for writing e-mail.
Keep in mind, that each topic goes for one person.
The whole rest is playing games on PC hardware. Sure these definitely keep PC hardware cheap, as these DO invest money in hardware components. - So.. even though the PC was always about gaming too..

, gamers are not the majority of PC users world wide. - And also they have no relevance for the OS/2 platform.. since the newest games do not run on OS/2.
Only a few people I know personally, are using more than one aspect of a PC.
So.. most likely Android and iOS appear to be what people need to do their thing.
They appear not to need what a PC can offer.
It`s been as it always was: PCs are only for those who know how to utilise such a machine for their needs.
Microsoft (mainly Microsoft) constantly tried to sell the PC platform and it`s (new) ease of use to the vast majority of potential buyers. Getting easier with each new Windows version... they say.. sure.. the whole opposite is the case.
But over the years, these people learned that ease of use is the same as reducing bureaucracy... just a trick to make people believe... but in the end it never works out. Things ALWAYS turn out more complicated in the end.
With mobile technology becoming more and more useful and reduced to what people REALLY only ever needed, in my eyes it`s more like things going back to normal again. PCs belong to professionals, and are wayyy to uber for the masses. They simply do not need the potential that a PC can offer.
And (still not finished), new developments even bring games to the cloud. The benefit is, that you do no longer need the ultra latest cutting edge hardware to play up2date games anymore; You can play them in a browser or special software that is linked to a special gaming cloud.
With this even weak hardware can open up new horizons for those interested to simply play computer games. No need for knowledge about hardware anymore, no need for specialised gaming hardware.. and of course the PERFECT copy protection, as the game is no longer client-side.
If this works out as intended, things WILL change drastically.
