Here one thing that is prevalent on this forum that I do not understand. Why do Microsoft fans think it has to be all or none? It is as simple as can be nowadays to mix and match. I do not support Microsoft, I do not support Apple, and I do not support Google, at least not support them in the way I think you mean it. I use Windows, OS X, Android, Chrome OS, Linux, iOS, and WP. I have an HP laptop, a Macbook, and a Chromebook. I use Lumia, Nexus, iPhone, and iPad devices. I use OneDrive, Google Drive, and Dropbox. I use Office and Google Docs. I use Cortana, Google Now, and Siri.
The so called cloud makes integration automatic, even between ecosystems. I do not suffer from fragmentation, and I have more features available to me than anyone who narrows it down to one ecosystem. I do of course have my primary choice for each department, but the others are available to step in if needed.
In short, there is little to no reason to be all in with, or "support", one of the big three. Pick and choose what works for you.
