MS Word is a sucky application on the Mac — especially the one I use, 2011. It looks like it was 100% ported and runs in X11, Java, Flash or Wine. I don't know if the latest one is like that, but I don't care because I'm not buying it anyways.
Maybe you shouldn't be using 6 year old software. If you are, maybe you shouldn't bash it without having used the latest MS Word.
Having the latest MS Office for Mac, I'll say using any of iWork becomes incredibly frustrating because it just doesn't have any power behind it. If you're making fliers to find your lost dog, or making a spreadsheet to add or subtract, it'll work, but anything more it just falls flat on its face.
On the contrary, Pages is elegant, text is as smooth as a baby's behind, editing tables is so easy a caveman can do it. I'm using it to make my own resume and template from scratch and it's impressed many people already.
I'd rather have only needed to impress once.
