I wish both Google and Microsoft would understand that you can't force change down users' throats. It needs to come naturally. They need to want it, and have it grow organically . Sure, forcing them will definitely bring you bigger "adoption" (for lack of a better word) faster, but it will also build up a lot of resentment, potentially negating any advantage you might have from ramming the change through, in the long…
Innovation is a funny thing, and interestingly, forcing change on end users is something for which Apple regularly receives praise. Or as Henry Ford pointed out, people wanted faster horses. Few people probably wanted rush hour gridlock either.
Denonymization of the internet had already happened long before G÷. Cookies and tracking data were collected for more than a decade before its rollout. G÷ just made it explicit, and Apple was already ahead via iOS and the app store and the SIM cards in all those phones. Microsoft was barely a step behind them, and for me? Well I think the Metro interface has huge advantage over WIMP. It's cloud identity integration that drove me from Windows 8. Installation was the Oh-Shit moment.
