Dear Yamiteru lori,
I will tell you one feature important to me in the writing I do, and that is the page preview. Word 97 had it on the crossbar above the page alongside cut paste etc., but they removed it in later versions. It is important to my writing because I take care for pages that are pleasing to the eye, the esthetics.
Generally speaking, the power of MS Word program is much greater than Apple's Pages program. MS Word has capabilities you might otherwise need to go to Adobe for.
I think it would be wonderful to have a very powerful word processor, on the order of MS Word but without trying to diversify into a lot of cumbersome stuff writers don't need.
Good luck, sounds like a very creative endeavor you have undertaken!
