Today the vast majority of people I know rarely use the browser on their phones. They interact with the internet through apps from various walled gardens, and even for news on the open web they are likely to install someone's app. Windows wouldn't have stood a chance if app development became so quickly an iOS/Android duoply.
Same goes for Nokia's Maemo and Meego. We nerds loved those OSs for being full-blown computer OSs, but the general public doesn't want a full-blown OS, they want a bunch of icons to corporate apps.
