[...] It's already done, can't y'all see it? People have accepted a reservation for 10, already. But most peolple are on automatic updates. All MS has to do is just push 10 onto everyone who is on automatic updates and reserved 10. Afterwards, if push comes to shove they can always say: "Oops! Sorry! We regret we misunderstood what you really wanted. But... so deeply sorry yet again: it's irreversible! And your current licence doesn't allow for downgrading either... Oh, well!
But I can concoct a more optimistic view, albeit less optmistic than yours: while keeping the numbers of XP, Vista and Win 8.0 about unchanged, let's admit reservation for 7 and 8.1+ was purely random (which surely is not true, but let's suspend disbelief)... if so, half the 7 and half the 8.1+ become 10... that, using the numbers from my original post about this, means, at the very least, 37% Win 10 overnight, which is much more than 8.1+ and 8.0 ever reached, even if considered together! I remain appalled at the sheer crooked brilliancy of it! In summary: "when you cannot seduce 'em anymore, well... simply con 'em!"
The more I read, the more a reflect on it, more sure I get about my forecast: Win 10 will have 35-40% of the user share when the numbers for August get released. Soon we'll know whether I'm right or not. And none of this through real product improving and added value!
