Okay. I had the chance to actually try it, and I guess those who reported to me for macnews.net.tc didn't actually _try_ anything besides the templates. If you choose 'Empty', it _does_ create an empty document and you _can_ just write away. Some keyboard shortcuts are a bit strange in the German language as far as I can tell, but otherwise, it looks and acts nicely. It _can_ export HTML, too, btw., but most users will probably use .doc or .pdf export more.
I'll give it another whirl now...
Ah, btw.: Pages has its own file format, which neither TextEdit nor MS Word can open so far. The file extension is .pages, which makes sense. Sadly, you cannot set the default file format to anything different, as for example .doc (which would be good if you intend to use Pages as a Word replacement but have to work with other people often...).
