What is the market share of Android devices in the mobile computing market 
he entire portfolio driving solid growth across the business. So Android and mobile computing is one aspect. But this is something that's much broader for us than one product line. Again, I go back to some of the things that I think differentiates us in the market of some things like our deep understanding of work flows and giving our customers the ability to leverage data at the edge to take more good real-time decisions to help to optimize and drive their businesses. So we're very excited about opportunities in all of our product lines. And there's several megatrends that support the growth like the on-demand economy.
Now specifically to mobile computing, we have seen great growth over several years now. And we're certainly very excited about the progress we made and the outlook we have for that business. There are several drivers for the growth we've seen. Now there's things like a number of new use cases they are being deployed that's underpinned by the strong portfolio of software capabilities that we have developed for our mobile computing portfolio. So this new use cases, I think, the best being long-term growth drivers. A couple of examples, a lot of our customers are looking to consolidate multiple devices or multiple applications onto our mobile computers. One example will be many verticals and many customers are using or have historically used dedicated PBX or wireless PBX phones for people. Now with our Workforce Connect application, we can consolidate that device and that use case onto our mobile computers. Another trend we're seeing is that our customers are looking to put more and more technology in the hands of all their people. So pushing technology further into the organization, so the trend of having a device for everybody is gaining a lot of traction. And I'd say also our big screen portfolio of mobile computers, so tablets and vehicle-mounted computers are seeing a lot of new use cases and interest also.
Now specifically to the Android transition, it clearly has been the catalyst for growth for us. We still have over 60% market share in Android. And the overall market -- mobile computing market is now more than 50% made up of Android devices. We still think that there's lots of potential in this market. We anticipate or we forecast that there is still about approximately 10 million legacy Windows devices in the market. And these devices are not all going to be converted to Android by 2020, when Microsoft stops supporting their older mobile operating systems. So this conversion cycle will take longer. We see good drivers. Our software continues to be a great driver and new devices -- we released some new devices specifically to capitalize on the warehouse transition, that's ramping up now, so our MC33 and MC93 products. So Android is clearly a great driver, but there's only one of several long-term drivers for our mobile computing business.

Quick follow-up. You're obviously investing a lot in software. You're acquiring your way into software data services, cloud applications, APIs and some. How is this expressed in your business model, because I know some folks looking in vain for the software line and it's not there. So just translate into margin improvement on the hardware side?

Well, first I'll give you a couple of thoughts around our software business and the strategy for it. We've gone from having kind of made historically, say downward devices to smarter devices and now more smart infrastructure. So very much focused on driving a performance edge for our customers and it's entire portfolio and software has become a great differentiator for us. Our Software DNA layer makes it lot easier for our customers to integrate, manage and their suites of Zebra products. So the -- specifically we launched the Savanna Data Services, that's a great new capability for us that enables Zebra and our partners and our customers to more easily access data as well as enable Zebra to monetize that data. It also then helps demo
