anyone who thinks iWork is better than Office is either a fool or a fanboy. Neither is better than the other. they serve different purpose.
plus, if you are willing to forgo those $400 and $500 version, Excel itself is worth $150. I generally don't like MS products but Office is an exception.
plus, the notes layout only found in Mac Office is great when you are taking lecture notes for the class. iWork just doesn't give you as good of a tool when you are trying to word process. iWork is great at making pages, but it is not a good word processor.
I do agree that Keynote is better than PowerPoint but there is a compatibility issue too.
Preach it man! I am a total and utter Mac love and MS hater - BUT - when it comes to Office software it cannot be beat - iWork has nothing on it, neither does NeoOffice, if you work in an office world like I do. Both of those are good enough for doing basic stuff, but Office has way more to offer. And the pricing is way lower than the Windoze versions. Professional is like $800 in Canada! That's crazy talk!
