I am disappointed in this myself. Pages is okay for basic stuff but as a writer I need real word processing.
I am especially miffed that they *say* they have added a word processing mode, when in fact they don't seem to have done that at all. I find this a bit deceptive.
If you look carefully at the tutorial, you can see that their idea of a word processing mode is simply to add page layout templates that conform to tasks that are usually done with a word processor. The "section breaks" are not section breaks but new template insertions, and if you hit the return key you won't get a new line, you will just confirm your changes on that template.
This f*cked up mixing of page layout tools and word processing tools is exactly what makes MS Word so unwieldy and bug-ridden. A lot of folks don't *want* to "click anywhere to begin" or base everything off of some tasteless pink bordered template. (I am talking about Word templates there), and those that do generally prefer it to be the default. Page layout and Word processing are different things; different metaphors for accomplishing the task. They don't mix well in Word and while I am sure Apple does it better, it's still not what most serious writers will want. I, (and a lot of people I would wager), want to use a word processor for most of my documents, not a PageMaker 3.0 clone.
I find it disturbing that Apple is now getting actively deceptive in their practices and advertisements. I haven't tried it yet, but it seems to me that there is *not* a word processor mode in Pages.
