iWork is something I would love to use, but I have to use Microsoft Office for school! I might get both though....
I don't really understand this though... I'm in school and I've used iWork for the last (almost) 2 years. Why is Office so gripping for you to state this? You can export to Word and PowerPoint if you really need to. Of course it doesn't look as good when you do, but it is still possible. Pages isn't quite as "advanced" as Word is, but I sure like using it more, and Keynote looks amazing compared to PowerPoint.
