Re: The irony is
The move to simpler devices has nothing to do with Microsoft, although their complete failure to spread their OS monopoly into mobile/tablet removed one obstacle to adoption. Few ordinary people need the power of a PC for the 'work' they do on them or a huge bloated OS stack to do it. The moment tablets and phones became good enough they stopped needing an overpowered PC.
Microsoft created the whole Win8 fiasco because they realised too late they had no presence in the post-PC world and no monopoly leverage because of that. So the Windows monopoly was abused to bludgeon us into accepting the crap they threw together for mobile. Hasn't worked so well, the users they targeted had already jumped ship to IOS and Android and have no problem using multiple OSes - the right one for each device.
