Alright, iWork is a really good program, but they don't have the great user interface that Office does. I have office but have tried iWork and here are the differences.
iWork comes with three programs, pages, keynote, and numbers, whearas office comes with five, entorage (an emailing program), Chat (a chat program, Word, Powerpoint, and Excel which I'm sure you know.
Entourage, is a great program and is worth the money.
Keynote is childish, although I am a child, it doesn't come with the costomability that powerpoint comes with. Also not nearly as good transitions, its transitions are cool for the few they have but they don't account for the amount office has.
I don't like pages because it doesn't come with WORDART which is awsome, also pages doesn't come with nearly the amount of fonts Word does.
I never use excel or numbers because I am in school and don't have to do any accounting but I can imagine that expirience makes a difference and for that I would have to go with excel.
Finally, there is the compatability issue. Although I think you can export iWork as .doc or others, it is just much harder to transfer files from iWork to a teacher or I don't know how old you are but also through a network at work.
If money is not an issue, I would definitly go with office. If money is an issue I would still go with office because of expirience, in a few years when mac revises iWork I am sure I will go with that, but for now it is definitely office.
Hope this helps, cause it took me many precious minutes to write, have fun, cause I certainly am with my mac, and sorry for all the appositives, we just learned them.
I finally made the switch to Mac! My Mac mini is floating on a truck somewhere right now. I need to buy an office program. I was thinking about iWork because of the price. Will iWork play nice with Microsoft Office files as far as import and export?
