My colleague Adrian Kingsley-Hughes laid it out the way it is. Windows Mobile is dead as a mobile platform given the lackluster adoption in the market. In spite of the massive effort Microsoft has put into it, there's such a tiny market share that even the company recently stated that mobile is not the firm's focus this year.
Many have said for a long time that Microsoft should move its phone line to Android. Kingsley-Hughes said it best: "One of those foes actually offers Microsoft a possible lifeline, and a way to make a bigger impact in the mobile space. It's time for Microsoft to dump Windows Phone and start making Android smartphones."
I agree. As he points out, Microsoft has done a superb job bringing its major software products to Android so there's a natural fit in moving its mobile hardware to the popular platform. There's even a way to do so that Microsoft could put its own stamp (and brand) on to make it its own.
It would require forking Android in a way to distinguish it from (without upsetting) the rest of the pack, something Microsoft could make in line with Windows while embracing Android's strengths.
Having used Remix OS for over a year, it's clear to me that this variant of Android is tailor-made for Microsoft. It's a full version of Android that has been designed to look and work much like Windows, right down to a file manager and familiar taskbar. Throw in the ability to run apps in windows on tablets and it's perfect for the Windows brand.
That's a good fit for the folks in Redmond and would allow them to put a Windows brand on it even though it is Android. Its Android apps already work out of the box on Remix OS and it wouldn't restrict those from OEM partners. It's a win-win for Microsoft.
This makes perfect sense to me. Remix OS runs Microsoft's apps so well. This is especially true of Office. It's a Microsoft variant for Android that already exists. It would only have to acquire the company and run with it. The smart people at Microsoft could turn Remix OS into a cool Windows version of Android while still supporting partners' Android hardware. Having a Microsoft "Windroid" phone would have a mass appeal.
