Re: The Terrible...
The VAST number of upvotes you've earned here tells me that I need tread carefully but I do feel it is important to counter some of the points you've made here.
Let me preface the following with an admission that Windows 8 through 10 are not perfect and no contained version is my primary OS.
With that said, let us begin...
"is to not recognise what their users wanted, namely Windows 7 with modest technical improvements."
Desktop mode in Win8 was a more stable and faster booting/shutting down version of Win7. Start menu was obviously changed but you hit the start button and you could start typing for what you wanted (same as Win7) or you were presented with a very different view that happened to be SIGNIFICANTLY more confirgurable than the old start thing and this ongoing complaint is 100% resistance to change. This is for a bag-standard user. I accept that an enterprise BOFH may have valid compaints. These complaints rarely show up in these threads.
'Instead they've got off on the idea that we'd want to put our data in their cloud, be profiled in our usage and turned into lumps of meat for sale in the advertising market to the highest bidder"
Even Ubuntu beat them to this. This is Microsoft being last to the party again (think how late Bing was). This isn't proof that they are ding the wrong thing. This is proof that they can't even see where the market is LEADING THEM. Yes, the majority of the market WANTS these rubbish "features".
"The PC market is dead-ish because of Windows 8/8.1"
This does not gel with observable history. The Win8.x UI and store was a response to mobile computing having long taken over in the consumer space.
"14% share and it's free? If anyone wanted it, craved it it'd be closer to 90%."
Pretty sure you're not factoring business into this calculation here.
"Open Office is just not very good"
Nether is Office Office. Jump ship. You'll get used to it.
