I could also note, re your claims about Office and corporate environments, that there were virtual machines that ran Windows and Office.

An anecdote:

One infamous Word/Excel version (6 iirc?) ran faster on emulated Windows using a different processor architecture than as an application. (I have never trusted a Microsoft product since then -- you never know when paying the strategy tax will rape functionality you depend on.)

But you almost certainly knew this.
