After years of speculation, Microsoft (NASDAQ:MSFT) has finally brought its well-known productivity software suite, Microsoft Office, to Apple's (NASDAQ:AAPL) iPad. Microsoft CEO Satya Nadella announced the move on Thursday, in line with previous rumors. This launch has been a long day coming, as Microsoft finally embraces its longtime rival's mobile platform.

In this segment from Friday's Tech Teardown, host Erin Kennedy and Motley Fool tech and telecom bureau chief Evan Niu discuss the groundbreaking move by Microsoft, and why this was a long time coming. Evan sees this as one of the most important strategic shifts coming from Microsoft in mobile in a long time, and says that the move is absolutely a win-win for both Microsoft and Apple. He sees this as potentially being a meaningful driver for Office 365 subscriptions, and a great sign that Microsoft is now taking the necessary steps to broaden its horizons.
