MS Office is a good point. But:

MS Office is available even for Android these days.

Otherwise Wine should work, and ain't there some cloud MS Office these days?

Except it doesn't. Office 2007 is over eight years old and runs with significant bugs.

The cloud versions are incomplete and don't work with plugins like Endnote. The cloud version of PowerPoint struggle with movies and large resources.
