Windows users might feel shortchanged by new reports swirling that Microsoft plans to release its redesigned touch-friendly Office suite to Android by the end of 2014 while the Windows version has been pushed back to spring of 2015. This rumour is in line with Microsoft CEO Satya Nadella's plans to have the company succeed in what he labels as the "post-post-PC era." This means making their services available to other platforms. Nadella has previously hinted that they plan to launch other major apps outside of Windows platform. We will keep you posted for any updates on this subject.
