OpenOffice is a horrible piece of software.

When I switched to Mac, I tried MS Office 2008, and it was buggy as hell, so I've been using OpenOffice, which sucked too, but slightly less (on Macs). Now MS Office 2011 is coming out, bugs fixed, looks great, UI/UX is great, so I started converting all docs back to MS format and will ditch OpenOffice in a couple of weeks.

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?

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 =)
