Only a few weeks after Samsung revealed it's preinstalling Microsoft's apps on the upcoming Galaxy S6 and S6 Edge, the two companies are getting even closer.Microsoft just announced that Samsung will also be bundling its Office apps, Skype, and OneDrive on select Android tablets sometime in the first half of the year. And when it comes to tablets Samsung sells to businesses, the Microsoft apps will also work together with its Knox security offering, which makes devices more secure and lets you switch between personal and professional profiles. That's what you call synergy, folks. Microsoft's been struggling to make a dent in the mobile market with Windows Phone, so it makes sense for it to team up with the biggest player on the largest mobile platform to promote its services. And of course, the integration with Microsoft's apps -- especially Office -- makes Samsung's wares a worthier option for businesses.
