Three of Microsoft's biggest mobile announcements from its Build 2014 conference were a new digital assistant called Cortana for Windows Phone 8.1, free Windows licenses for sub-9-in. devices and universal Windows apps that will run on Windows desktops, Windows smartphones and, someday, Xbox.
The universal Windows apps announcement got the least attention of the three, but the move demonstrates Microsoft's commitment to improving its share of the tablet and smartphone markets.
In a blog post late Wednesday, Microsoft revealed more details that pegged the universal Windows apps to a single consolidated pricing structure of 99 cents or $1.29 per app. The company also plans to simplify the tiered revenue-sharing model it has with developers to a 70/30 model by the end of the year.
As a group, the universal apps, Cortana and free Windows licenses for some devices show that Microsoft is accelerating its drive to increase its share of the global smartphone and tablet markets. It now has a paltry 4% of the smartphone market and its share of the tablet market is an even sorrier 2%.
The innovations also show that the company is braced to try new things under the leadership of new CEO Satya Nadella.
While the improvements sound promising and garnered plenty of headlines, analyst Jack Gold of J.Gold Associates dubbed them "first small steps." What Nadella and top managers are primarily trying to do is show off a "new philosophy that Microsoft wants to be easier to do business with and is more interested in listening to customers," he said.
On the other hand, Van Baker, an analyst at Gartner, said the company's mobile moves "make Microsoft pretty appealing to developers."
Universal Windows apps take leap ahead
On the first day of Build, David Treadwell, corporate vice president of the operating system group, announced a universal app scenario that allows developers to build a single code base for an application that can run across Windows desktop, Windows Phone and eventually the Xbox. A single app could have the same interface for a phone, a tablet and a desktop, or the developer could customize the interface for each form factor.
Microsoft later Wednesday published two blog posts that described how developers can build universal Windows apps running on the same Windows runtime, enabled by both the new Windows Phone 8.1 and the new Windows 8.1 Update.
"Developers have a common way of building and architecting apps for phones, tablets and PCs; from how they handle suspend and resume and do background processing to the way they manage in-app security," said Kevin Gallo, director of the Windows developer platform.
For building universal apps, Microsoft also released Visual Studio 2013 Update 2 RC as a download.
Todd Brix, general manager of Windows apps and Windows Store, also published a blog post showing an example of the new symbol that customers will see in coming weeks for a unified Windows app. It will be up to developers to decide whether they want to charge users per-app or per-device for a universal app -- or whether they want to release an app for free, he said.
Brix also said that the existing tiered revenue sharing model for apps will be phased out as of Dec. 31, with Microsoft adopting an industry standard 70/30 revenue split. "We're confident that the vast majority of developers will be more successful within the more unified Store structure and policies," Brix said.
Will universal apps fly?
"Windows 8.1 will encourage developers to move to universal Windows apps," Gartner's Baker said. "What's the downside? If your app can run across Windows Phone, Windows Tablets and PCs, why wouldn't you do that? It increases the appeal to consumers."
The ability for apps to port across all of a user's devices "is huge," said Ramon Llamas an analyst at IDC. In theory, the plan could push Microsoft ahead of Android and iOS, he added. "Where does Google stop and Chrome begin and where does iOS stop and the Mac OS begin?" he asked.
But Gold said Microsoft has been trying to consolidate app development for years. "The vision of one code base for all platforms is nice, but it won't happen in the short term due to the need for optimizing the OS to each device," he said. "That means there will continue to be specific apps and environments for different platforms for three to four years, at least."
Several analysts said Microsoft needs to eventually combine the Windows Store and the Windows Phone Store to attain the ultimate unified app environment.
Having a single store "would make it much easier for users in discovery and management of apps," said Carolina Milanesi, an analyst at Kantar Worldpanel.
But Gold said that there's still some appeal to keeping phone apps separate from other Windows apps, in separate stores. "Phone users often want to go to a specific place to find apps, like going to a specialty store like a sporting goods store instead of a full-blown retailer like Walmart," he said.
Patrick Moorhead, an analyst at Moor Insights & Strategy, said he would have liked it if Microsoft had talked more at Build about what's known as "modularity" -- a concept that applies to scenarios where a user with a phone or phablet could walk into an office, place the device on a desk and have it connect wirelessly to a display, mouse and keyboard with all the data processing done on the phone with connections to the Internet and cloud data and services.
Moorhead said that unified apps are a kind of modular development approach to enable apps to be written once for many devices. "In that scenario," he explained, "it is easier to work with or watch content on any device."
