I never thought I would say this...first, Libre/OpenOffice both suck - OUT LOUD. I hate the way java programs feel. But...

As passionate Linux user, I am happy with almost everything about it but I use Linux primarily to provide technology solutions; secondarily, it is my desktop; I switch between F18 and a beautiful Mac.

While I evangelize it as a server, I can't push it to my business users for 1 reason: they know, love, and won't use anything other than MS Office. It would be huge coup for me, and the people I support, if MS did port Office to Linux.

If you ask the average user, "What OS are you using?" they would just shrug say, "idunno". So, I think the changing of the OS would be a noticeable but ultimately irrelevant shifting of the landscape around them. Though there would be a slight learning curve, navigating the file-system in the "Save As" windows, I doubt they would care but without MS Office the conversation is a non-starter.

On the other side, I've recently started using Windows again; the corporate laptop was forced on me, what can I say? But, coming from 4 years of solid {Open,Libre}Office use, I can say that MS Office is 1) far more mature, that's a given but 2) it just "feels" better.

MS Office has a lot of features that I'm reacquainting myself with that the open Office packages just don't have or are buggy.

I use Google Docs more than either of them though. It's platform-independent, has all the features I would need, has hot-key support, great templates, and it feels good.

For better or worse, I would take 1) Google Docs over all else, 2) MS Office, 3) Gedit, and 4) not {Open,Libre}Office unless the others were unavailable.
