The road to operating system (OS) convergence is already paved, and many IT leaders are set to roll down that path.\nDespite a recent denial from Google regarding reports that it planned to merge Android and Chrome this month, Apple, Google and Microsoft are clearly making moves designed to merge their mobile and desktop OSes. However, none of them are quite ready to make the full transition to a single OS for all of their devices.\nThese companies may still be weighing the potential gains and sacrifices of blending their OSes \u2014 iOS and OS X, Android and Chrome, Windows 10 Mobile and Windows 10 \u2014 but many IT leaders are prepared, anxious even, for what they see as a foregone conclusion. The unified OS won't be a panacea for all IT responsibilities and challenges, however, and while CIOs are generally excited about convergence, some notable disadvantages exist.\nBenefits of OS convergence outweigh IT concerns\n"From an IT leader perspective [convergence] makes it easier," says Aaron Gette, CIO at Bay Club, a lifestyle and fitness company. "At the end of the day \u2026 we're driving to a federated model of managed systems."\nThe unification of mobile and desktop platforms should mean fewer repetitive tasks as part of CIOs' daily corporate IT management responsibilities, Gette says. "The less OSes that you have to manage, especially from the same manufacturer, the better."\nGreg Meyers, corporate vice president and CIO of Motorola Solutions, is less enthusiastic, because of the potential shortcuts and limitations that could come as a result of converged environments. "In the enterprise world, mobile apps are usually a watered down version of their desktop or browser counterparts," he says. "I am not sure how rich applications like Salesforce, Oracle or SAP can ever be abstracted enough to work well on purely a mobile-like interface."\u00a0\n[Related Feature: How Motorola Solutions and its 22,000 workers ditched Microsoft for Google]\nMobile apps, by nature, are designed to be simple, and that may not bode well for full-featured enterprise apps, he says. Nonetheless, Meyers says he expects mobile and desktop software to eventually unite as developers purposefully create more consistent apps for devices with different screen sizes and capabilities. What is unclear is just how well that will translate in the much richer world of enterprise apps. "As a matter of principle, it's always simpler to develop against fewer platforms, but the IT function will need to hire a lot more designers if it plans to build multimodal applications," Meyers says.\u00a0\nIT is increasingly a services-based industry, and progressive apps that work across mobile and desktop with similar experiences help enable OS convergence, according to Adam Codega, IT operations leader at business analytics firm Swipely. The unification of mobile and desktop will be particularly challenging for organizations that aren't nimble and ready to support a variety of devices and platforms, he says. "We haven't even stopped and realized it yet, but [IT leaders] are actually already getting ourselves ready for a converged OS because the device, and even more so the OS, continues to matter less and less."\n[Related News Analysis: Apple's Cook looks to grow its $25 billion enterprise business]\nBay Club's Gette thinks desktop and mobile convergence will be mostly beneficial to IT, particularly for businesses that already operate in a cloud-based environment, but he also says all of the pieces are not yet in place for Apple, Google or Microsoft to fully merge their respective platforms.\nMicrosoft closest to OS convergence, Chrome a non-factor\u00a0\nOf the three major players, Microsoft is the closest to delivering a truly unified OS, according to Gette. Microsoft was the first platform provider to move toward convergence with previous versions of Windows, but none of those attempts proved to be fruitful, according to both Gette and Codega.\nFor IT, Chrome is a "non-factor at the moment," according to Meyers, because Chrome is not a fully capable OS, at least not compared to Windows 10 or Mac OS X.\nGette agrees. "The focus at Google has always been very splintered," says Gette. "Whether the Android OS ever translates to desktop, I don't know. I don't see a lot of value in the Chrome OS, so Google to me is more of a non-player."\nCodega says Swipely customers uses Chrome-powered devices as kiosks for credit card processing and analytics, but he thinks the Android experience is much different than Chrome, so they're the least obvious candidates for seamless convergence.\nEnterprise insignificant to Apple's convergence plan\nWhile iOS and OS X continue to integrate and look more and more similar, Apple's strategy for convergence has little to do with IT requirements or considerations, according to Gette. "Apple [is] never going to bend to the enterprise \u2026 I feel like they're driving towards [convergence], but they're less concerned about whether the enterprise accepts it or not."\nGette expects the major mobile and desktop platforms to eventually merge and says it's "ridiculous" for any of the leading providers to deny that it's already happening. However, he worries convergence could come at the expense of innovation and result in fewer choices for IT professionals. "I don't think any of us want to see is one or a few players dominating the marketplace and innovation suffers."
