Mobile Ubuntu vs Android

Android is undoubtedly the mobile OS to beat in 2013. iOS has loyal fans, but it simply can't achieve Android's volume driven by multiple OEMs producing phones and tablets in countless form factors.

That said, Android has problems. Big ones. The first is Google itself. If you don't opt in to at least a substantial subset of Google's services, you can forget using an Android device. The second is ongoing patent issues, both for Android and manufacturers that use it. Finally, both Apple and Microsoft are ahead of Google in terms of enterprise management and deployment

Ubuntu can address all of these issues on mobile devices, bringing a platform which is at once trusted in the enterprise, unencumbered by patent and privacy issues, and still more open than Android.

Will mobile Ubuntu kill Android?
No.

Can it steal its thunder, though, and put a squeeze on Google, especially in the enterprise?
Yes.
