Yeah sure, go ahead and manage all the references for a 20 page paper for hand and tell me how much time you waste. I use a combo of Papers + Endnote + Word, and I get my referencing done in no time, if I were to do it by hand in Pages it would take hours. And you're just being childish. I don't blame the tools, Pages is a fine piece of software for home use and probably most uses in the office. But for work requiring references, it's garbage out of the box.
And spelling and grammar checking is better in Word, and as english is now my first language I appreciate this while writing my papers.
We recently assembled a 1100 page (in A5 ... about half of US letter size) grant with Word on a MBP and it worked fine. I wouldn't want to do that with any other program (LaTeX, iWork, OpenOffice.) And then, we made a password protected PDF for submission.
