Microsoft CEO Satya Nadella hasnt been leading the company very long, but hes already put forward a very clear message: the new Microsoft wants its best apps and services on all platforms, and its not playing favorites. The launch of Office for iPad was clear evidence of that, and now it seems Microsoft is preparing to bring a touch-optimized version of its productivity suite to Android — months before it rolls out a Windows equivalent. ZDNet is reporting that the redesigned mobile Office will arrive on Android by the end of 2014. Thats great news for Android tablet owners, but its also likely to disappoint and even anger some Windows users, who feel Microsoft is ignoring its own backyard while bringing this polished and finger-friendly Office experience to Windows rivals. But this is the trajectory that Microsoft must follow to succeed in what Nadella recently labeled a post-post-PC era. There are going to be Windows devices and there are going to be other devices and we have to make sure our services run on all of them, he said during last weeks Code Conference.
