Cruft
So, which of the following do you think affords you more screen real estate for word-processing "out of the box": Word 2011, Pages, or Pages for iPad? (Note: the Mac screenshots are from a 1440 x 900 Macbook Pro 15" display.)
Apple did all the things to Pages I would have recommended, and then some. So its ratio of usable space to cruft is even better. Meanwhile, I don't know if Google Docs has overtaken MS Word in terms of user share, but it probably deserves to, and it makes pretty good use of screen real estate (it wastes a toolbar's worth of vertical space on the document name up top, but otherwise is much the same as Pages). As for Word… nothing has changed.
