Office isn't really worth it anyway unless you;
A. Need to collaboorate on documents with Windows users, and/or
B. Are a student and can get it cheap
I don't have it, but Pages gets pretty good reviews here, and it's far cheaper. if you don't need spreadsheets, it would be fine.
NeoOffice is good (I use it), if a bit slow to load, and it has almost all of the features that Word has.
If you're set on Office, wait until the Universal Binary version is out, which could be any time, but is likely to be a couple of months at the least. In the meantime you should try out the free alternatives.
