We can handle that

Why don't you use a Mac?
I like Microsoft office.

Wouldn't necissarily expect it to be such a big concern but it truthfully is. Have you tried using OpenOffice in the X11 on OS X? It's a difficult task, it really just doesn't go with the flow. And it's hard to get running, not very intuitive at all. And when I say not intuitive, I generally use the terminal more than Finder out of preference, while it will vary from person to person I really mean really not intuitive bordering completely unusable. When they have a more native like version it will probably be fine.

The Office for Mac operates relatively well, while the version I have certainly has it's occasional faults, they are few and far between.

So backing up from the technical standpoint, it really smoothes over a concern of usability involved with the use of a Mac for this function. It takes out the outcastness of the Mac as compared to PC in this wise. Good ad.
