Microsoft tried this a few years ago. Getting top 10 apps like Instagram took a lot of time -- and presumably money too, although that was of course never disclosed.<p>When Instagram did make a native Windows Phone app, it was feature incomplete and stuck in permanent beta. I don&#x27;t think they ever released a final version.<p>Most other top 10 apps never did ports. At the same time, Microsoft was also spending quite extravagantly to get small indie devs making Windows apps through initiatives like &quot;App Campus&quot;. Those didn&#x27;t make a dent either.<p>Paying their way to a mobile ecosystem was a complete failure for Microsoft. Even with its deficiencies, I&#x27;m sad that Windows Bridge for Android (&quot;Project Astoria&quot;) is dead. The iOS bridge is nowhere close in practical use. Windows 10 universal apps don&#x27;t have developer mindshare in the mobile space. Windows 10 Mobile is pretty much dead.
