The only person I know that uses KOffice works at a small business that is all Linux, and he likes it. That's not a very large sample or detailed review, I know. I would probably stick with OpenOffice in a Windows environment, just because there is likely to be a very short learning curve, and I know that it won't screw up formatting when I save in different file formats. But what the heck, download KOffice and give it a shot, like the earlier post suggested. Maybe it is the greatest thing ever, and you can be in front of the crowd on adoption and down the road you can make smug comments like, "Oh, yeah, KOffice is great, I've been using it for years." Or, if you don't like it, delete it.
