Microsoft's ambitions for Windows 10, cellular PCs and its potential folding mobile device have an undeniable Achilles Heel - the app gap. But there may be a solution on the horizon.

Microsoft's personal computing efforts are often met with legitimate criticisms about its app gap. It lacks the developer support critical to the modern app model. The current model has shortcomings, however. As app stores grow app discoverability becomes increasingly difficult. Furthermore, the average user uses only six apps regularly, doesn't frequent app stores and rarely downloads new apps. In fact, web properties are engaged more frequently than apps. As 5G networks, Progressive Web Apps (PWA) and processors like Qualcomm's Snapdragon 845 begin to take root, some challenges of the current app model (which are problematic for all platforms) will be solved. This shift toward platform-agnostic PWAs may help Microsoft escape the app gap-imposing confines of the current app model. It will be the progressive implementation of 5G networks and modern processors, the maturation of PWAs and multi-generational waves of cellular PCs and folding-mobile devices that may help Microsoft overcome the app gap. Let's break it down. Will Windows phone fans finally get the device of their dreams?

How Microsoft is prepping the enterprise for its folding mobile Surface

What should Microsoft name its folding mobile Surface? What is 5G?

According to Qualcomm CEO Steve Mollenkopf 5G is, unlike the incremental steps from 1G to 4G, a new technology that will transform connected computing. Qualcomm will begin 5G rollout in 2019. It'll make accessing apps on the web as fast as the memory on your phone. 5G will handle 1000 times more traffic than current networks, will be 10 times faster than 4G LTE and have half millisecond latency. 5G will enable autonomous cars, secure remote healthcare, immersive AR and more. Furthermore, Qualcomm's 845 Snapdragon processor will "make accessing the apps on the web as fast as the memory on your phone," said Alex Katouzian SVP of Qualcomm Semicon. If Microsoft's folding mobile device launches with it in late 2018, it'll be capable of accessing web apps as fast as it would native apps. This first-gen device will be positioned to benefit from evolving PWA technology. What are PWAs?

"Progressive Web Apps combine the best of the web and the best of apps." Users aren't required to install them, and they become more powerful as users use them. Google spearheaded PWAs in Chrome and Microsoft's Edge browser will also support them. PWAs work for any user, on any form factor, offline or on low-latency networks, feel like apps, remain updated, are discoverable, installable and can be shared via a link. Since mobile users frequent web properties more than apps PWAs are more consistent with human behavior than apps. Here's how PWAs and 5G will benefit Microsoft. Qualcomm's 845 (and later) chips and high capacity-low latency networks make web apps as quick as native apps. Microsoft's Project Westminster can create hybrid PWA-UWP apps enabling notifications, Cortana integration, Live Tiles, Windows Store distribution and more. Developers might embrace PWAs (which are not web wrappers) because they're easier to build and can target a broader base. Progressive disintegration of the app gap
