Sigh.
"they would tell you the progress we've made in [Windows] 8.1 – because we have a first-party product at Microsoft – is far superior to anything we've ever delivered"
No. They wouldn't. They would tell you that the market wants Windows 7 with a touch screen overlay. I've got Windows 8, I've even tried convincing myself to like it, but after nearly a year of using it I have to say it's crap. It's Windows trying to be Android and ending up as neither with a closed eco system with bugger all worthwhile apps and could very well be the last, broad-reach OS they ever produce.
Not to mention they have vendors putting Windows 8 on non-touchscreen devices! You have to SERIOUSLY have a screw loose to buy one of these products (I seem to be doing a lot of "downgrades" to Windows 7 for people at the moment who have bought new laptops that have come with Win 8 and can't wait to get it off). It's like buying a non-touch screen phone and putting Android on it and then wondering why it's difficult to use. Windows 8 is a non-starter, and instead of listening to the people who actually buy and use it they are listening to their own marketing bullshit and developing business strategy on the back of that. Doomed to failure, it will just take a long time due to thier massive bank balance and patent trolling, which is about the only profitable part of the business they have left for the future.
