Rumors of a Surface phone from Microsoft have swirled for years. But there's far more to it.

I don't believe Microsoft will ever release a Surface Phone. I do believe Microsoft will launch a category-defining ultimate mobile device that will play to the company's strengths rather than its proven weakness. Smartphones are Microsoft's Achilles Heel. Thus, Microsoft's ultimate mobile device will not be a phone. Many critics claim that due to Microsoft's poor mobile ecosystem a Surface-branded ultimate mobile device, even with all the bells and whistles, is doomed to failure. I made a similar argument not long ago. I appealed to Microsoft to exhibit a show of force in various ecosystem-building areas at BUILD 2017. Microsoft needs to make great, even unorthodox, efforts to woo developers to its ecosystem and ensure the platform's relevance in the future of increasingly mobile personal computing. There are specific areas — UWP, apps, mindshare, partnerships and more — which Microsoft must address if the "Surface phone" is to succeed.

It's all in how Microsoft markets the ultramobile Surface PC: it's not a phone. Recognizing strengths and weaknesses Microsoft's way back into mobile won't be with a dramatic splash. It will have to be a slow, subtle and methodic progression — first dipping the toe, then slowly wading into ever-deeper water.

Microsoft will have to focus on its strengths, forsaking the traditional approach to mobile. That old model failed Microsoft, leading to retrenchment, refocusing on enterprise, and a less-than-one-percent market share with only a handful of OEM partners. Smartphones are not Microsoft's forte. Its strength is in PCs, as its decades-long dominance proves. The success of the Surface brand is proof of Microsoft's talent for innovation.

Despite its silence concerning mobile (and past failures) Redmond must bring something that plays toward its strengths to the mobile space. The smartphone is currently the key to a company's broader ecosystem. Thus, a personal mobile device, not necessarily a smartphone, is a necessary component of Microsoft's UWP and Windows 10 Device family. Microsoft's pocketable mobile option will be a PC, not a phone. There's demand for Windows laptops and 2-in-1 PCs

Microsoft's strength in PCs isn't founded only on its decades-long legacy as the provider of the dominant PC platform. Recent data that takes into account the company's category-defining strategy with the Surface progresses that legacy into the current era of personal computing and mobility. Research firm IDC reported on the success of Windows laptops and 2-in-1s, finding that such devices are desired by consumers, and even predicting growth in the market over traditional tablets. Furthermore, JD Powers 2017 US Tablet Satisfaction Study found that customers are more satisfied with the productivity-focused Microsoft Surface than the consumption-focused iPad and Android tablets. Riding the momentum

Microsoft's ultramobile Surface should, therefore, be marketed as a PC. Consumers want PCs, after all. How might Microsoft market to the masses? Like the Surface Pro, it will likely have a heavy enterprise focus but with consumer appeal. It'll also be positioned to inspire manufacturing partners to mimic the concept and design. The only visuals we have of what this potential device might look like are from patents and Microsoft Future Vision videos.

Did Microsoft give us a glimpse of its Surface phone vision? This doesn't guarantee anything, but history has set a precedence. Skype Real-time Translation (and other technologies) were foreshadowed in Microsoft's future vision videos. Surface Studio patents were also reflective of what came to market, so too may these folding device patents eventually make it to reality (though, admittedly, they're probably a long way off). Evolving a concept Microsoft can advance the HP Lap Dock concept to be a more integrated experience to market the ultramobile Surface.

Redmond can promote what will initially appear to be a powerful, smaller and more portable Surface Book. In reality this "laptop" would be a peripheral which houses a fold-able Window 10 ultramobile cellular PC in the base which powers the peripheral (and wirelessly projects to the detached "digital clipboard") via Continuum. As a Windows 10 PC users can use Win32 (and Store) apps which are practical in a "laptop" environment. Users could also experience all other Windows 10 features from inking, Windows Mixed-Reality and game streaming.
