A bit more research would be nice
>Windows 8/8.1 does not appear to be being picked up by consumers or businesses. Microsoft lost a year >on Windows 8 as OEMs didn’t deliver PCs or tabs,
Let's see the not delivered systems from SONY (Vaio Duo11/12), Lenovo (Helix, TPT2, Thinkpad Yoga), Dell (Latitude 10), Samsung (Ativ 500t, Ativ700, Tab3).... and that is just the pen equiped tablet pc from 2012/2013. There are more touch only tablets and touch enabled notebooks around. Guess the OEM DID deliver quite a few units....
> while consumers stayed away from machines as businesses upgraded to Windows 7 instead.
And check how a company / admin that does know their jobs do a large scale upgrade. This is a LOT more effort than Auntie Mays surfstation and involves lengthy compliance checks. Add a quick look at typical client system replacement cycles (3-5 years), start with 1999/2000 (many big companies used that as a "new client" roll in) and you find many companies starting the replacement process well before Win8 was out.
Besides 13 percent market share, that is almost 10x the client market share of that funny DIY OS some people spend their free time with, isn't it. Or twice as must as that "pretty but costly" hardware/software combo with the half eaten fruit.
