Squid,
I've also done some additional work to determine how you might be able to use the iPad to post your stories.
Go to the App Store, and install (for free) one or all of the following browsers: Chrome, Mercury or Terra. Each allows you to change your "user agent" string to pretend you are NOT on an iPad.
Using Chrome, select the option "Request Desktop Site" and you should get the full editor in GA.Stories.
Under Mercury and Terra, select the option User Agent and change to Mac OS X Safari so that it no longer thinks you are on an iPad.
I took some content from a Word document and I pasted it into GA.Stories using Chrome and it maintained most of the formatting.
