I agree that Office for Mac 2011 is a large improvement, but it still doesn’t feel quite right to me. Have you seen Apple’s iWork suite?

http://www.apple.com/iwork/

It provides the most commonly used functionality from Word, Excel, and Powerpoint in a simpler interface that I find much easier and pleasant to use (certainly much more Mac-like), at half the price of Microsoft’s Home/Student edition (a 30 day trial is available).

I like Keynote a lot and use it all the time for presentations, I think it's better than Powerpoint. Also, compatibility isn't that much of an issue here because I just present from my Macbook all the time.

But I prefer Word & Excel over the Apple/OpenOffice counterparts. Here compatibility also matters, as I routinely send Word & Excel files to lawyes, investors, etc. You don't want your files looking like crap with those guys =)
