Well, you want to be using what your clients can read, it doesn't have to the the same software. This is true for most file formats - audio, video, image/graphics (the latter more restricted due to other entrenched proprietary formats) - but the 'office' space (no pun intended) is still suffering from decades of abuse of its position os operating system vendor by Microsoft. Windows is only getting worse with every release so it is just smart business sense to steer away from it and things depending on it. Microsoft Office is one of the few remaining reasons often quoted for staying with this deteriorating platform so there are other incentives to move away from it. The best moment for moving away from Windows was years - or decades - ago. The second best moment is now.
