As one who has to deal with incoming (massive) .doc files from customers, partners and consultants, I'll assure everyone that this "stop using MS Office" requirement would be impossible.

I have a recent build of NeoOffice (OO packaged for OS X) on my MBP, and while I'm quite happy using it for casual day-day interaction with small, simpler Word documents (< 100 pages, < 5 Mbytes) - It's nowhere close to prime time for reading in larger, complex Word Documents; for any serious integration with Microsoft, you absolutely, positively, _have_ to have the native applications on your desktop. And even then it's not a slam dunk if someone created with a different version of MS Office on a different platform.

And, given that we all have to deal with those documents occasionally (Unlike me, who has to deal with them every day) - That means Microsoft continues to sell licenses to people who only use their software to deal with the rare Microsoft Document that blows up their copy of OO.

Seriously - Pages on the Macintosh (Awesome), or OO is more than enough for 99% of the worlds document creators - the only reason those 99% _need_ to purchase Microsoft Office anymore is for compatibility.

That's why Microsoft fights standards like ODF tooth and nail - once people have a choice, they'll make it.
