Android IS the new Windows
While the differences between Android and Windows are huge, there's no doubt that in terms of importance the reign of the Windows platform is lessening -- I hesitate to use the word waning just yet -- and instead mobile platforms such as Android and iOS have seen themselves thrust into the spotlight.
As we transition from the era of the PC into the post-PC era, Google's Android platform has, through a combination of luck and hard work, found itself the dominant operating system on mobile devices, and as such is in a great position to control the direction that smartphones and tablets take over the coming years.
This is not to say that there aren't challenges, the largest of which is getting upgrades to existing users, but I have no doubt that Google is working hard behind the scenes with handset makers and carriers to solve this.
In terms of sales and a grip on the future direction of the mobile market, Android IS the new Windows.
Android is NOT the new Windows
Android is not the new Windows. Not in terms of enterprise ubiquity, glacial development speeds, or code bloat, and certainly not in terms of monopoly. Although it can claim dominance in the smartphone market, it has a long way to go to penetrate the enterprise.
Still, it isn't a stretch to see Android dominating in the enterprise as tablets and other mobile devices, along with greater acceptance of BYOD, become more commonplace. However, to become a truly ubiquitous computing platform, Android needs to have the cache of Apple, the enterprise tools of Windows, and outstanding brand and market differentiation.
Windows became THE platform of the PC era because of good timing, a solid ecosystem, good marketing, and a lack of competition. Android can become THE platform of the post-PC era only through high-value, incredibly innovative products. It's started down that road, but the outcome is anything but a done deal.
