iWork's compatibility is horrendous, though.
Tables made from .pages file can't even show properly on .docx, .rtf nor .doc...
iWork is actually pretty sad except for Keynote, which is far superior than Power Point by all means.
However, Excel 2008 and Word 2008 is a little better than iWork in my opinion..
I own both and there's a reason why I chose Excel/Word over Numbers/Pages... Specially Numbers.... ew.
And that's me after using iWork '09 since the week of release too...
Anyways, if you're used to shortcuts or the behaviors of any Office before.. You'll need some time to get used to iWork's way of doing things...
Just make sure you run all the updates as soon as you get the Office suite... runs much snappier and smoother for me.
For 99.99, I'd say Office is a better deal.
