Although Pages 2 does not export to a Word doc very well if it contains a lot of image formatting and such.
As a test I opened the Newsletter template in Pages and added 3 more pages containing the same information. I then exported it to Word and emailed to friends on a Mac and a PC containing Word. The friend on the PC said when he attempted to open the file Word kept opening continuous blank pages up to about 15 until he forced it to quit. The Mac friend opened the Word doc and instead of having 4 pages he got 6 pages where the images and text were unevenly distributed amongst.
So I would suggest for simple text and simple text formatting exporting a Pages document to Word is ok, but for anything else probably not unfortunately.
