Apple Australia has published iPad content to their site, and some keen-eyed observers have noticed what's missing.
The list of features explained on the site includes much of what we saw yesterday -- Safari, Mail, YouTube, video ... all but iBooks and the iBookstore. Scroll down to the bottom of the page and you'll see a footnote stating that iBooks will be U.S.-only at launch.
In the meantime, all iPhone/iPod touch apps will run on the iPad, international uses can grab the Kindle app [Free - iTunes link] (the irony is not lost on us), Classics [Free - iTunes link] or any of the other ereaders in the App Store [iTunes link].
Of course, we're a few months out of launch so things might change. But we're not holding our breath.
