The Galaxy S6 comes with all the key Google apps preinstalled, as one would expect. But it also is preloaded with Microsoft's OneNote note-taking app and OneDrive cloud storage app/service. Samsung's spec sheet says the S6 and S6 Edge will offer users 115 GB of free OneDrive storage for two years. From screen shots on various sites, it looks like Skype is preloaded on these new Samsung devices, too, and available via a Microsoft apps folder.
In recent months, Microsoft's interest and ability to build really nice cross-platform applications for iOS and Android has become more evident. OneNote, OneDrive, Skype and the evolving Office universal apps are available for iOS, Android and Windows/ Windows Phone.
But today is the first time (I believe) that Microsoft has struck a deal with a non-Windows/Windows Phone OEM to preload any of its apps and services on its devices. Technically, I guess you could count the Apple-Microsoft deal via which Microsoft's Bing search is the Web-search fallback for Siri as another example of an OEM preload deal. But to me, today's Microsoft-Samsung deal is more of a true first in this category.
With this new deal, Microsoft just upped the importance of showing users why Windows/Windows Phone is supposedly a better platform than the competition. Microsoft officials continue to claim that the level of service integration that Microsoft will offer Windows users will be superior to what it offers users of its software and services on iOS and Android.
