I use Pages a lot, and the version tracking works well when I want to share a document with an editor.
I do have some wishlist items - I wish it had easy keyboard shortcuts for promoting and demoting headings like word always had, and I wish it was more straightforward to modify a style (the ‘update this style’ box can be a bit random about when it will work).
The iCloud syncing between mac, ipad, iphone has proved really useful.
