If you use a Mac, you should check out NeoOffice – OpenOffice.org for MacOSX. I’ve been using NeoOffice for a couple of months now. It works very well, and eliminates my need for MS Office. I don’t use an office suite much, which is why I’m quite thankful to these guys that I don’t need to shell out the cash for MS Office. NeoOffice is far nicer than using OpenOffice under X, as well.
Unfortunately, it sounds like it will be a while before OOo comes to the Mac. Still, I’m happy with what I’ve got in this package.
